Narrated AbuHurayrah:

The Prophet ﷺ said: If any of you prays two rak'ahs before the dawn prayer, he should lie at his right side.

Marwan ibn al-Hakam said to him: Is it not enough that one of us walks to the mosque until he lies at his right side? According to the version of Ubaydullah, he (AbuHurayrah) replied: No.

This statement (of AbuHurayrah) reached Ibn Umar. He said: AbuHurayrah exceed limits on himself. He was asked: Do you look askance at what he says? He replied: No, but he dared and we showed cowardice. This (criticism of Ibn Umar) reached AbuHurayrah. He said: What is my sin if I remembered and they forgot?

حَدَّثَنَا مُسَدَّدٌ، وَأَبُو كَامِلٍ وَعُبَيْدُ اللَّهِ بْنُ عُمَرَ بْنِ مَيْسَرَةَ قَالُوا حَدَّثَنَا عَبْدُ الْوَاحِدِ، حَدَّثَنَا الأَعْمَشُ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ " إِذَا صَلَّى أَحَدُكُمُ الرَّكْعَتَيْنِ قَبْلَ الصُّبْحِ فَلْيَضْطَجِعْ عَلَى يَمِينِهِ " . فَقَالَ لَهُ مَرْوَانُ بْنُ الْحَكَمِ أَمَا يُجْزِئُ أَحَدَنَا مَمْشَاهُ إِلَى الْمَسْجِدِ حَتَّى يَضْطَجِعَ عَلَى يَمِينِهِ قَالَ عُبَيْدُ اللَّهِ فِي حَدِيثِهِ قَالَ لاَ . قَالَ فَبَلَغَ ذَلِكَ ابْنَ عُمَرَ فَقَالَ أَكْثَرَ أَبُو هُرَيْرَةَ عَلَى نَفْسِهِ . قَالَ فَقِيلَ لاِبْنِ عُمَرَ هَلْ تُنْكِرُ شَيْئًا مِمَّا يَقُولُ قَالَ لاَ وَلَكِنَّهُ اجْتَرَأَ وَجَبُنَّا . قَالَ فَبَلَغَ ذَلِكَ أَبَا هُرَيْرَةَ قَالَ فَمَا ذَنْبِي إِنْ كُنْتُ حَفِظْتُ وَنَسُوا .
