عَنْ يَزِيدَ بْنِ كَيْسَانَ اسْتَأْذَنْتُ عَلَى سَالِمِ بْنِ أَبِي الْجَعْدِ وَهُوَ يُصَلِّي فَسَبَّحَ لِي، فَلَمَّا سَلَّمَ قَالَ: إِنَّ إِذْنَ الرَّجُلِ إِذَا كَانَ فِي الصَّلَاةِ يُسَبِّحُ وَإِنَّ إِذْنَ الْمَرْأَةِ أَنْ تُصَفِّقَ
It is narrated from Yazid bin Kaisan, he says: I sought permission from Salim bin Abu Ja’d while he was praying, he replied to me by saying “Subhan Allah.” Then when he finished the prayer with salam, he said: When a man is praying, his way of granting permission is to say “Subhan Allah,” and for a woman, it is to clap.
