Narrated 'Aishah, wife of Prophet ﷺ:
That the Prophet ﷺ once offered (tarawih) prayer in the mosque and the people also prayed along with him. He then prayed on the following night, and the people gathered in large numbers. They gathered on the third night too, but the Messenger of Allah ﷺ did not come out to them. When the morning came, he said: I witnessed what you did, and nothing prevented me from coming out to you except that I feared that this (prayer) might be prescribed to you. That was in Ramadan.

حَدَّثَنَا الْقَعْنَبِيُّ، عَنْ مَالِكِ بْنِ أَنَسٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ، عَنْ عَائِشَةَ، زَوْجِ النَّبِيِّ ﷺ أَنَّ النَّبِيَّ ﷺ صَلَّى فِي الْمَسْجِدِ فَصَلَّى بِصَلاَتِهِ نَاسٌ ثُمَّ صَلَّى مِنَ الْقَابِلَةِ فَكَثُرَ النَّاسُ ثُمَّ اجْتَمَعُوا مِنَ اللَّيْلَةِ الثَّالِثَةِ فَلَمْ يَخْرُجْ إِلَيْهِمْ رَسُولُ اللَّهِ ﷺ فَلَمَّا أَصْبَحَ قَالَ " قَدْ رَأَيْتُ الَّذِي صَنَعْتُمْ فَلَمْ يَمْنَعْنِي مِنَ الْخُرُوجِ إِلَيْكُمْ إِلاَّ أَنِّي خَشِيتُ أَنْ يُفْرَضَ عَلَيْكُمْ " . وَذَلِكَ فِي رَمَضَانَ .
