Amal yang paling dicintai Allah adalah memberi makan dan mengucapkan salam
Imam Nasa'i : 4914أَخْبَرَنَا قُتَيْبَةُ قَالَ حَدَّثَنَا اللَّيْثُ عَنْ يَزِيدَ بْنِ أَبِي حَبِيبٍ عَنْ أَبِي الْخَيْرِ عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍوأَنَّ رَجُلًا سَأَلَ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَيُّ الْإِسْلَامِ خَيْرٌ قَالَ تُطْعِمُ الطَّعَامَ وَتَقْرَأُ السَّلَامَ عَلَى مَنْ عَرَفْتَ وَمَنْ لَمْ تَعْرِفْ
Narrated to us [Qutaibah], he said : has told us [Al Laits] from [Yazid bin Abu Habib] from [Abu Al Khair] from [Abdullah bin 'Amr] that a man asked the Messenger of Allah peace be upon him; Which Islamic (practice) is the best?" He said: "You feed and greet people you know and those you don't know."
