Sunan Abi Dawud, Hadith 1665 ⓘ

Buhaysah reported on the authority of his father: My father sought permission from the Prophet. (When permission was granted and he came near him) he lifted his shirt, and began to kiss him and embrace him (out of love for him). He asked: Messenger of Allah, what is the thing which it is unlawful to refuse? He replied: Water. He again asked: Prophet of Allah, what is the thing which it is unlawful to refuse? He replied: Salt. He again asked: Prophet of Allah, what is the thing which it is unlawful to refuse? He said: To do good is better for you.

حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ، حَدَّثَنَا كَهْمَسٌ، عَنْ سَيَّارِ بْنِ مَنْظُورٍ، - رَجُلٍ مِنْ بَنِي فَزَارَةَ - عَنْ أَبِيهِ، عَنِ امْرَأَةٍ، يُقَالُ لَهَا بُهَيْسَةُ عَنْ أَبِيهَا، قَالَتِ اسْتَأْذَنَ أَبِي النَّبِيَّ صلى الله عليه وسلم فَدَخَلَ بَيْنَهُ وَبَيْنَ قَمِيصِهِ فَجَعَلَ يُقَبِّلُ وَيَلْتَزِمُ ثُمَّ قَالَ يَا رَسُولَ اللَّهِ مَا الشَّىْءُ الَّذِي لاَ يَحِلُّ مَنْعُهُ قَالَ ‏"‏ الْمَاءُ ‏"‏ ‏.‏ قَالَ يَا نَبِيَّ اللَّهِ مَا الشَّىْءُ الَّذِي لاَ يَحِلُّ مَنْعُهُ قَالَ ‏"‏ الْمِلْحُ ‏"‏ ‏.‏ قَالَ يَا رَسُولَ اللَّهِ مَا الشَّىْءُ الَّذِي لاَ يَحِلُّ مَنْعُهُ قَالَ ‏"‏ أَنْ تَفْعَلَ الْخَيْرَ خَيْرٌ لَكَ ‏"‏ ‏.‏
