Musannaf Ibn Abi Shayba 9:1310

'Abd al-A'la narrated to us, from Yunus, from al-Hasan, that 'Aqil ibn Abi Talib married a woman from Banu Jusham. So they prayed for him, saying, "With concord and sons." He said, "Do not say that." They said, "How should we say it, O Abu Yazid?" He said, "Say: 'May Allah bless for you, and may He bless upon you,' for that is what we used to say, or we were commanded to do so."
