Muwatta Malik 1728

حَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ إِذَا عَادَ الرَّجُلُ الْمَرِيضَ خَاضَ الرَّحْمَةَ حَتَّى إِذَا قَعَدَ عِنْدَهُ قَرَّتْ فِيهِ ‏"‏ ‏.‏ أَوْ نَحْوَ هَذَا ‏.‏

Yahya related to me from Malik that he had heard from Jabir ibn Abdullah that the Messenger of Allah, may Allah bless him and grant him peace, said, "When a man visits an invalid, he plunges into mercy to the extent that when he sits with him, it settles in him," or the like of that
