“Do not crack your fingers during the prayer.”  

ابن ماجة:٩٦٥ – حَدَّثَنَا يَحْيَى بْنُ حَكِيمٍ حَدَّثَنَا أَبُو قُتَيْبَةَ حَدَّثَنَا يُونُسُ بْنُ أَبِي إِسْحَاقَ وَإِسْرَائِيلُ بْنُ يُونُسَ عَنْ أَبِي إِسْحَاقَ عَنِ الْحَارِثِ عَنْ عَلِيٍّ

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ تُفَقِّعْ أَصَابِعَكَ وَأَنْتَ فِي الصَّلاَةِ
