Sayyiduna Hasan (may Allah be pleased with him) says that (his uncle) Sayyiduna Aqil bin Abi Talib (may Allah be pleased with him) came to Basra and married a woman from Banu Jusham. According to custom, people congratulated him and said: «بالرفاء والبنين» (that is, congratulations on your marriage with hopes of goodness, blessing, harmony, affection, and sons). Upon this, he said: Do not say this; the Messenger of Allah (peace and blessings be upon him) forbade us from saying «بالرفاء و البنين» and instructed us to say: «بَارَكَ اللّٰهُ لَكَ وَبَارَكَ عَلَيْكَ» , meaning "May Allah bless you and may blessing be upon you."
