It is narrated from Hazrat Yusuf bin Abdullah bin Salam that I had the honor of companionship with Hazrat Abu Darda (may Allah be pleased with him), I used to acquire knowledge from him. When the time of his departure from this world approached, he said, "Inform the people of my final moments." So I went out to inform the people. When I returned, the whole house was filled and people were standing outside as well. I said, "I have informed the people and now the house is filled with people inside and outside." He said, "O people! I heard the Prophet say: Whoever performs ablution and does it well, then prays two rak'ahs with complete humility, Allah surely grants him whatever he asks for, whether immediately or after some delay." He further said, "O people! Avoid looking right and left in prayer, for such a person's prayer is not valid. If this happens in voluntary prayers, then do not let it overcome you in obligatory prayers."
