Sunan Ibn Majah, Book 29, Hadith 3384 (In-Book) ⓘ

Kathir bin Sulaim narrated that he heard Anas bin Malik say: “The Messenger of Allah said: ‘Whoever would like Allah to increase the goodness of his house, should perform ablution (wash hands) when his breakfast is brought to him and when it is taken away.’”

حَدَّثَنَا جُبَارَةُ بْنُ الْمُغَلِّسِ، حَدَّثَنَا كَثِيرُ بْنُ سُلَيْمٍ، سَمِعْتُ أَنَسَ بْنَ مَالِكٍ، يَقُولُ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏ "‏ مَنْ أَحَبَّ أَنْ يُكْثِرَ اللَّهُ خَيْرَ بَيْتِهِ فَلْيَتَوَضَّأْ إِذَا حَضَرَ غَدَاؤُهُ وَإِذَا رُفِعَ ‏" ‏ ‏.‏
