[Machine] The Prophet ﷺ was praying in his room one night when some of his companions came and prayed with his prayer. He reduced it then entered the house, then came out and did that again. He kept praying and then leaving. When morning came, they said, "O Messenger of Allah, we prayed with you last night and we would love for you to prolong your prayer." He said, "I knew of your presence and deliberately did that."
أَنَّ رَسُولَ اللهِ ﷺ كَانَ ذَاتَ لَيْلَةٍ يُصَلِّي فِي حُجْرَتِهِ فَجَاءَ أُنَاسٌ مِنْ أَصْحَابِهِ فَصَلَّوْا بِصَلَاتِهِ فَخَفَّفَ ثُمَّ دَخَلَ الْبَيْتَ ثُمَّ خَرَجَ فَفَعَلَ ذَلِكَ مِرَارًا كُلُّ ذَلِكَ يُصَلِّي وَيَنْصَرِفُ فَلَمَّا أَصْبَحَ قَالُوا يَا رَسُولَ اللهِ صَلَّيْنَا مَعَكَ الْبَارِحَةَ وَنَحْنُ نُحِبُّ أَنْ تَمُدَّ فِي صَلَاتِكَ فَقَالَ قَدْ عَلِمْتُ بِمَكَانِكُمْ وَعَمْدًا فَعَلْتُ ذَلِكَ
