It is narrated from Sayyiduna Abu Ayyub al-Ansari (may Allah be pleased with him) that the Prophet of Allah (peace and blessings be upon him) said: "Keep the marriage proposal hidden, then perform ablution and perform it well, then pray as much as Allah has decreed for you, then praise your Lord and glorify Him, then say: O Allah, You have power and I have no power; You know and I do not know, and You are the Knower of the unseen. If, in Your knowledge, so-and-so (a woman), and let him name her by her name, is good for me in my worldly life and my Hereafter, then decree her for me", or he said: "then ordain her for me."
