وَمَا كَانَ لِمُؤْمِنٍۢ وَلَا مُؤْمِنَةٍ إِذَا قَضَى ٱللَّهُ وَرَسُولُهُۥٓ أَمْرًا أَن يَكُونَ لَهُمُ ٱلْخِيَرَةُ مِنْ أَمْرِهِمْ ۗ وَمَن يَعْصِ ٱللَّهَ وَرَسُولَهُۥ فَقَدْ ضَلَّ ضَلَٰلًۭا مُّبِينًۭا
And it becometh not a believing man or a believing woman, when Allah and His messenger have decided an affair (for them), that they should (after that) claim any say in their affair; and whoso is rebellious to Allah and His messenger, he verily goeth astray in error manifest.
Surah Al-Ahzaab(33:36)

Conditions
Chapter: Conditions in Waqf (i.e., religious endowment)
Narrated Ibn `Umar:
Umar bin Khattab got some land in Khaibar and he went to the Prophet (ﷺ) to consult him about it saying, "O Allah's Messenger (ﷺ) I got some land in Khaibar better than which I have never had, what do you suggest that I do with it?" The Prophet (ﷺ) said, "If you like you can give the land as endowment and give its fruits in charity." So `Umar gave it in charity as an endowment on the condition that would not be sold nor given to anybody as a present and not to be inherited, but its yield would be given in charity to the poor people, to the Kith and kin, for freeing slaves, for Allah's Cause, to the travelers and guests; and that there would be no harm if the guardian of the endowment ate from it according to his need with good intention, and fed others without storing it for the future."
