وَعَنْ أَنَسٍ قَالَ: كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا قَالَ: «سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ» قَامَ حَتَّى نَقُولَ: قَدْ أَوْهَمَ ثُمَّ يَسْجُدُ وَيَقْعُدُ بَيْنَ السَّجْدَتَيْنِ حَتَّى نَقُولَ: قَدْ أوهم. رَوَاهُ مُسلم
Anas said: When the Prophet (ﷺ) said, “God listens to him who praises Him,” he stood so long that we thought he had omitted something; then he would prostrate himself and sit between the sajdas so long that we thought he had omitted something. Muslim transmitted it.
