[Machine] That the Messenger of Allah ﷺ prohibited him from exchanging his skill, even if he had allowed it, we would have made an exception.
أَنْ يَتَبَتَّلَ فَنَهَاهُ رَسُولُ اللهِ ﷺ عَنْ ذَلِكَ وَلَوْ أَجَازَ لَهُ لَاخْتَصَيْنَا

أَنْ يَتَبَتَّلَ فَنَهَاهُ رَسُولُ اللَّهِ ﷺ وَلَوْ أَجَازَ لَهُ ذَلِكَ لاَخْتَصَيْنَا
