Sunnan Abu Dawud Collection: ::Book Number 11:: Hadith # 2135
Narrated Qays ibn Sa'd: I went to al-Hirah and saw them (the people) prostrating themselves before a satrap of theirs, so I said: The Apostle of Allah (peace_be_upon_him) has most right to have prostration made before him. When I came to the Prophet (peace_be_upon_him), I said: I went to al-Hirah and saw them prostrating themselves before a satrap of theirs, but you have most right, Apostle of Allah, to have (people) prostrating themselves before you. He said: Tell me , if you were to pass my grave, would you prostrate yourself before it? I said: No. He then said: Do not do so. If I were to command anyone to make prostration before another I would command women to prostrate themselves before their husbands, because of the special right over them given to husbands by Allah.
