[Machine] The Prophet ﷺ used to pray one night in his room and some people came and prayed with his prayer. So, he lightened his prayer, then he entered the house and came out repeating all of that, praying. When morning came, they said, "O Messenger of Allah, you prayed and we would have liked for you to prolong your prayer." He said, "I knew your position and deliberately did that."
أَنَّ النَّبِيَّ ﷺ كَانَ يُصَلِّي ذَاتَ لَيْلَةٍ فِي حُجْرَتِهِ فَجَاءَ أُنَاسٌ فَصَلَّوْا بِصَلَاتِهِ فَخَفَّفَ فَدَخَلَ الْبَيْتَ ثُمَّ خَرَجَ فَعَادَ مِرَارًا كُلَّ ذَلِكَ يُصَلِّي فَلَمَّا أَصْبَحَ قَالُوا يَا رَسُولَ اللهِ صَلَّيْتَ وَنَحْنُ نُحِبُّ أَنْ تَمُدَّ فِي صَلَاتِكَ قَالَ قَدْ عَلِمْتُ بِمَكَانِكُمْ وَعَمْدًا فَعَلْتُ ذَلِكَ
