Muhammad Bin Yahya...
Muhammad Bin Yahya, from Muhammad Bin Ahmad, from Ahmad Bin Hilal, from Marwak Bin Ubeyd, from Nasheet Bin Salih, from Hisham Bin Al Hakam, (It has been narrated) from Abu Abdullah -asws having said: ‘Rasool-Allah -saww said: ‘It is from an understanding of the guest that he would not Fast voluntarily except by the permission of his host; and from the obedience of the wife to her husband is that she would not be Fasting voluntarily (optional Fasts) except by his permission; and from the correctness of the slave and his obedience, and his correctness to his master that he would not be Fasting voluntarily except by the permission of his master and his instruction; and from the righteousness of the child that he would not Fast voluntarily except by the permission of his parents, and their instruction – or else the guest would be ignorant, and the wife would be disobedient, and the slave would be wicked, disobedient, and the child would be disloyal’.
Ali Bin Muhammad Bin Bundar and someone else, from Ibrahim Bin Is’haq, by a chain he mentioned, from Al Fuzayl Bin Yasaar, (It has been narrated) from Abu Ja’far -asws having said: ‘Rasool-Allah -saww said: ‘When a man enters a city, so he is a guest upon the ones who are in it, from the people of his Religion, until he departs from them.
And, it is not befitting for the guest that he should be Fasting except with their permission, perhaps they would be making something, so it would spoil upon them. And, it is not befitting for them that they should be Fasting except with the permission of the guest, perhaps he would be embarrassed, so he would desire the food, but he would leave it for them’.
