"I was thinking of forbidding Ghilah until I remembered that it is done by the Persians and Romans" -(one of the narrators) Ishaq said: "(They) do that -and it does not harm their children." (Using translation from Nasāʾī 3326)
سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ لَقَدْ هَمَمْتُ أَنْ أَنْهَى عَنِ الْغِيلَةِ حَتَّى ذَكَرْتُ أَنَّ فَارِسَ وَالرُّومَ يَفْعَلُونَ ذَلِكَ فَلَا يَضُرُّ أَوْلَادَهُمْ
