Urging one's kith and kin to Obey Allah and refrain from evils
وَعَنْ أَبِي حَفْصٍ عُمَرَ بْنِ أَبِي سَلَمَةَ عَبْدِ اللَّهِ بْنِ عبد الأسد ربيب رَسُولَ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ قَالَ: كُنْتُ غُلاَمًا فِي حَجْرِ رَسُولِ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ وَكَانَتْ يَدِي تَطِيشُ فِي الصَّحْفَةِ، فَقَالَ لِي رَسُولُ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ : يَا غُلاَمُ سَمِّ اللَّهَ تَعَالَى، وَكُلْ بِيَمِينِكَ، وَكُلْ مِمَّا يَلِيكَ فَمَا زَالَتْ تِلْكَ طِعْمَتِي بَعْدُ. ((مُتَّفَقٌ عَلَيْهِ)).
'Umar bin Abu Salamah (May Allah be pleased with him) reported: I was a boy under the care of Messenger of Allah (ﷺ), and my hand would wander about in the dish. Messenger of Allah (ﷺ) said to me "Mention Allah's Name (i.e., say Bismillah before you start eating), eat with your right hand and eat from what is near to you". I always followed this way of eating after this incident. [Al-Bukhari and Muslim].
