Sayyiduna Aqil (may Allah be pleased with him) married a woman from Banu Jusham bin Sa'd. People came to him and, while escorting him as a bridegroom, began saying: "May you have harmony and sons." He said: "Do not say that." The people asked: "Then what should we say, O Abu Yazid?" He said: "Say: 'May Allah bless you and send blessings upon you'; we used to be commanded to say this."
