عَن عمر بن أبي سَلمَة قَالَ: كُنْتُ غُلَامًا فِي حِجْرِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَكَانَتْ يَدِي تَطِيشُ فِي الصفحة. فَقَالَ لِي رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ «سم الله وكل يَمِينك وكل مِمَّا يليك»

Jabir told that when they were with God’s messenger at Marr az-Zahran and were plucking the fruit of the arak tree he said, “Keep to its black ones, for they are the most pleasant.” He was asked if he had shepherded sheep and replied, “Yes; has there been a prophet who did not shepherd them?” (Bukhari and Muslim.)
