We know The rainbow is a bad Omen. Is one allowed to tell a friend when he sees one, in order to allow him to make a Bracha or should he hold back as it is a bad sign?

    "We know The rainbow is a bad Omen." Source? Based on Parshat Noach it would seem to be a very good omen. And why would we have a bracha of praise for something that's bad?

Per Mishna Brura (229:1), when one sees a rainbow he should not inform a friend about it, but rather make a bracha and keep it to himself.

    Thanks for the source I still wonder about the Bracha why should my friend lose out? Oct 27, 2011 at 12:42

As noted by Gershon, this is Mishnah Berurah citing the Chayei Adam. It seems that there might be room for manipulation according to other posekim. Thus:

Q. (252) Mr. Danny Persoff: Is there an Issur to look at a rainbow? A. The Shulchan Aruch (229:1) writes that it is prohibited to look at a rainbow "B'yotair" for a prolonged period of time. The Gra (ibid.) writes that there is no prohibition of R'eeyah, briefly looking, for one needs to see the rainbow in order to make the Bracha; rather, the Issur is Histaklut, staring intently. (See also Machazit Hashekel ibid.) The Iyun Yaakov writes that it is a Mitzvah to see the rainbow in order to recite the Bracha. However, the Mishna Berura (229:1) quotes the Chayai Adam who maintains that one should not tell a friend that there is a rainbow in the sky.

Regarding the reason for the Issur, the Gemara (Baizah 16a) writes that the rainbow symbolizes the glory of Hashem, therefore, it is inappropriate to look at the rainbow just as it would be wrong to look at the glory of Hashem, K'veyachol. (See Shmot 24:10-11 regarding B'nai Yisrael looking at Elokai Yisrael.) The Tosfot Harid explains the comparison between a Keshet and Hashem: Just like the colors of a rainbow are indiscernible, one can not tell where one color ends and another begins, so too with regard to Hashem, we can not truly know Him, and we must symbolize that ignorance by abstaining from staring at the rainbow. (See the M'eeri Baizah16a, where he writes that the Issur is not to stare at the rainbow, rather, to delve into the mysteries of the Pesukim that deal with the rainbow in Parshat Noach.)

For instance, the Aruch HaShulchan, which some people pasken like over the Mishnah Berurah, writes in the same siman, 229 that the prohibition is just staring, not simply looking. And he does not cite the Chayei Adam about not telling a friend, and so does not bring it down lehalachah. This might well make sense, since you would not be causing your friend to violate any issur, if you are just telling him so that he can make the beracha.

Of course, consult your local Orthodox rabbi, who will in all likelihood tell you to follow the Mishnah Berurah. :)

  • In halacha shiur not long ago, we read IIRC the Yalkut Yosef, who said that one should tell a friend, and not the Mishnah Berurah, FWIW.

Rabbi Moshe Kohen of Gerba Tunisia writes (Bris Kehuna Ma'areches Kuf, Ois Daled):

קשת. המנהג פשוט פה דכל מי שרואה הקשת אומר לחבירו או לחביריו לברך על זה ומ״ש ה׳ כף החיים ז״ל סי׳ רכ״ט אות א׳ בשם הה״א והא״ח דאין להגיד לחבירו שיש קשת משום מוציא דבה. לע״ד אינו נראה דאדרבא אנחנו שמתים ונותנים תודה וברכה לה׳ אשר בחסדו כרת הברית הזאת שלא להשתית את עולמו עוד וכ״ן דעת רבותינו בגמרא ובפוסקים ודעת הראשונים שתיקנו ברכה זו. ועוד דאדרבא טפי עדיף להגיד לזולתו כדי שכל אחד הרואה ואחד השומע ישימו לב לשוב אל ה׳. כי בראותם כזאת יכירו וידעו כי העולם כולו במצב קשה ונורא לולי רהמיו והםדיו ברוך הוא. ולכן לע״ד יפה נהגו פה להגיד:

The minhag pashut (common custom) is to tell someone else about the rainbow. That which the Kaf Hachaim and others say that it is like telling bad things, I don't agree with. It's the opposite; we are thanking Hashem for keeping us alive and not punishing us like we deserve. Also, seeing the rainbow brings persons to tshuva when they realise what a bad position the world is. Therefore it's correct for people to tell others.

I personally would say slightly different. If Hashem didn't want everyone to know about the rainbow, why show it just to a select few? Is it they who are the bad people and have to mend their ways while the others who don't see it themselves are all tsadikim and have no tshuva to do?

    I like making a post where I can also provide some chiddush and not just repeat what others say.

    +1, Thanks for taking the effort to make your answers clear and easy to read. (Have a look at how I have edited for ideas how to make things even clearer, which will result in making it easy for others to read, and thus upvoting).

R. Yitzchak Abadi has a responsum in which he was asked his question:

Shu"t Ohr Yitzchak 2:89:3

המ"ב (ס"ק א') הביא את החיי אדם שכתב דאם ראה את הקשת אין כדאי להגיד לחבירו דהוא מוציא דיבה ובספר ברית כהונה (מערכת ק') פליג על החיי אדם הנ"ל וכתב דאדרבה אנו שמחים בזה ועל זה אנו מברכים ע"ש איך ההלכה

תשובה אין לזה שום מקור שאסור לומר לחבירו ואיך אפשר לסמוך על מה שאין ידוע מקורו ובסמוך נביא ראיה מספר חסידים דלא כהחיי אדם אלא שיש להודיע לחבירו כדי שיברך

The Mishnah Berurah (Se'if Katan 1) brings the Chayei Adam who writes that if one sees the rainbow it is not proper to tell his friend, because he is spreading an evil report. And the book Brit Kehunah (Ma'areches Kof) disagrees with the aforementioned Chayei Adam and writes that on the contrary we are happy about this and this is what we are making a blessing on, see there. What is the [final] halachah?

Answer: There is no source at all that it is forbidden [for one] to say to his friend [that there is a rainbow]. And how can we rely on something whose source is unknown? And nearby we will bring a proof from the Sefer Chasidim not like the Chayei Adam; rather, one should inform his friend in order that he make the blessing.

The "nearby proof" is a reference to what he writes two questions later (2:89:5) where he notes that the Sefer Chasidim (807) discusses someone who was told during the repetition of Shemoneh Esrei that there was a rainbow and he went outside to make the blessing, and the Sefer Chasidim makes no mention of an issue of spreading an evil report by telling the guy about the rainbow.
