Hadith 13213

(حديث مرفوع) حَدَّثَنَا عَبْدُ الصَّمَدِ ، حَدَّثَنَا حَمَّادٌ ، حَدَّثَنَا ثُمَامَةُ ، عَنْ أَنَسِ بْنِ مَالِكٍ ، أَنَّ أَصْحَابَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَتَوْهُ لَيْلَةً فِي رَمَضَانَ ، فصَلَّى لَهُمْ فَخَفَّفَ ، ثُمَّ دَخَلَ فَأَطَالَ الصَّلَاةَ ، ثُمَّ خَرَجَ فَصَلَّى بِهِمْ ، ثُمَّ دَخَلَ فَأَطَالَ الصَّلَاةَ ، فَفَعَلَ ذَلِكَ مِرَارًا ، فَلَمَّا أَصْبَحَ ، قَالُوا : يَا رَسُولَ اللَّهِ ، أَتَيْنَاكَ فَفَعَلْتَ كَذَا وَكَذَا ! ! فَقَالَ : " مِنْ أَجْلِكُمْ فَعَلْتُ ذَلِكَ " .
It is narrated from Hazrat Anas (may Allah be pleased with him) that once in the month of Ramadan, the Prophet (peace and blessings be upon him) came out and led a short prayer and then left. After quite some time, he came again and led a short prayer and then went back again and stayed inside for a long time. When morning came, we said, "O Messenger of Allah (peace and blessings be upon him)! We were present tonight, you came and led a short prayer and then went home for a long time?" The Prophet (peace and blessings be upon him) said, "I did so because of you."
