وَعَنْ عَبْدِ اللَّهِ بْنِ عَمْرِو بْنِ الْعَاصِ رَضِيَ اللَّه عَنْهُمَا أَنَّ رَجُلاً سَأَلَ رَسُولَ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ: أي الإِسْلاَمِ خَيْرٌ؟ قَالَ: تُطْعِمُ الطَّعَامَ، وَتَقْرَأُ السَّلاَمَ عَلَى مَنْ عَرَفْتَ وَمَنْ لَمْ تَعْرِفْ . ((مُتَّفَقٌ عَلَيْهِ)).
Abdullah bin 'Amr bin Al-'as (May Allah be pleased with them) reported: A man asked the Messenger of Allah (ﷺ): "Which act in Islam is the best?" He (ﷺ) replied, "To give food, and to greet everyone, whether you know or you do not." [Al-Bukhari and Muslim].
