Please read the hadith that other wives of The Holy Prophet did not know what The Holy Prophet told about their rights. We also know that daughter of The Holy Prophet Lady Fatima got angry with Abu Baker because Abu Baker did not give her FADAK. Hazrat Abu baker told the same hadith ” Our property is not to be inherited, and whatever we leave is to be spent in charity” . It is strange that if the matter was related with the daughter of The Holy Prophet, she did not know about it but others knew about that matter?
We all know that FADAK was given to Lady Fatima by The Prophet in His life. Then it was taken back from her by the first Caliph Abu Baker. When Lady Fatima asked back FADAK from Abu Baker, she was told a hadith against it. The question rises here: how come The Holy Prophet say anything but himself The Prophet act against it?
