The animals and trees prostrate before you! And as long as they do it, we are more rightful in doing this to you (i.e. to prostrate before you)."

We were travelling with the Prophet (Peace be upon him) when suddenly a camel came near "and prostrated to the Prophet (Peace be upon him)" The Prophet (Peace be upon him) asked: Who is the owner of this camel? At this some youngsters from Ansaar said that it belongs to them. The Prophet asked them: What have you done with it? They replied: We have been putting load (of water) on it since the past 20 years, now when he has become old and gathered excessive mass on itself so we made up our minds to slaughter him and distribute the meat amongst our friends. The Prophet (Peace be upon him) asked: Would you sell it to me? They replied: Ah! It is yours O dear Prophet (salallaho alaihi wasalam). The Prophet said, keep it but take good care of it until natural death reaches it.The Sahaba asked: O Prophet (Peace be upon him) we are more deserving of prostrating to you than the animals. The Prophet (Peace be upon him) replied: It is not allowed for anyone. Sunan Darami Vol 1 Hadith no: 17 under the chapter Page 22-23 Authenticated by Hussain Saleem Asad

6) And the Prophet (peace and blessings of Allaah be upon him) said: “If I were to command anyone to prostrate to anyone other than Allaah, I would have commanded women to prostrate to their husbands. By the One in

Whose hand is the soul of Muhammad, no woman can fulfil her duty towards Allaah until she fulfils her duty towards her husband. If he asks her (for intimacy) even if she is on her camel saddle, she should not refuse.”
