"I have given my son a slave of mine as a present." The Messenger of Allah said: "Have you given a present to all of your children?" He said: "No." The Messenger of Allah said: "Then take (your present) back." (Using translation from Nasāʾī 3673)
أَنَّ أَبَاهُ أَتَى بِهِ رَسُولَ اللهِ ﷺ فَقَالَ إِنِّي نَحَلْتُ ابْنِي غُلَامًا كَانَ لِي فَقَالَ رَسُولُ اللهِ ﷺ «أَكُلَّ وَلَدِكَ نَحَلْتَهُ؟» قَالَ لَا قَالَ رَسُولُ اللهِ ﷺ «فَارْجِعْهُ»
