Sahih al-Bukhari 2837
Narrated Al-Bara:
On the day (of the battle) of Al-Ahzab (i.e. clans) I saw the Prophet (ﷺ) carrying earth, and the earth was 
covering the whiteness of his `Abdomen. And he was saying, "Without You (O Allah!) we would 
have got no guidance, nor given in charity, nor prayed. So please bless us with tranquility and make 
firm our feet when we meet our enemies. 
Indeed (these) people have rebelled against (oppressed) us but never shall we yield if they try to bring 
affliction upon us."
حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي إِسْحَاقَ، عَنِ الْبَرَاءِ ـ رضى الله عنه ـ قَالَ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَوْمَ الأَحْزَابِ يَنْقُلُ التُّرَابَ وَقَدْ وَارَى التُّرَابُ بَيَاضَ بَطْنِهِ، وَهُوَ يَقُولُ لَوْلاَ أَنْتَ مَا اهْتَدَيْنَا وَلاَ تَصَدَّقْنَا وَلاَ صَلَّيْنَا‏.‏ فَأَنْزِلِ السَّكِينَةَ عَلَيْنَا وَثَبِّتِ الأَقْدَامَ إِنْ لاَقَيْنَا‏.‏ إِنَّ الأُلَى قَدْ بَغَوْا عَلَيْنَا إِذَا أَرَادُوا فِتْنَةً أَبَيْنَا‏.‏
