حَدَّثَنَا أَبُو كُرَيْبٍ، مُحَمَّدُ بْنُ الْعَلاَءِ حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا عَبْدُ الْحَمِيدِ بْنُ جَعْفَرٍ، عَنْ سَعِيدِ بْنِ أَبِي سَعِيدٍ الْمَقْبُرِيِّ، عَنْ أَبِي شُرَيْحٍ الْخُزَاعِيِّ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " الضِّيَافَةُ ثَلاَثَةُ أَيَّامٍ وَجَائِزَتُهُ يَوْمٌ وَلَيْلَةٌ وَلاَ يَحِلُّ لِرَجُلٍ مُسْلِمٍ أَنْ يُقِيمَ عِنْدَ أَخِيهِ حَتَّى يُؤْثِمَهُ " . قَالُوا يَا رَسُولَ اللَّهِ وَكَيْفَ يُؤْثِمُهُ قَالَ " يُقِيمُ عِنْدَهُ وَلاَ شَىْءَ لَهُ يَقْرِيهِ بِهِ " .
(The period of the entertainment of a guest is three days, and utmost kindness and courtesy is for a day and a night. =" It is not permissible for a Muslim to stay with, his brother until he makes him sinful. They said: Messenger of Allah, how he would make him sinful? He (the Holy Prophet) said: He stays with him (so long) that nothing is left with him to entertain him.
