عَنِ الْبَرَاءِ بْنِ عَازِبٍ رَضِيَ اللَّهُ عَنْهُ قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَأْتِينَا إِذَا قُمْنَا إِلَى الصَّلَاةِ فَيَمْسَحُ عَوَاتِقَنَا أَوْ صُدُورَنَا وَكَانَ يَقُولُ: ((لَا تَخْتَلِفُوا فَتَخْتَلِفَ قُلُوبُكُمْ))، وَكَانَ يَقُولُ: ((إِنَّ اللَّهَ وَمَلَائِكَتَهُ يُصَلُّونَ عَلَى الصَّفِّ الْأَوَّلِ أَوِ الصُّفُوفِ الْأُوَلِ))
Sayyiduna Bara’ bin Azib (may Allah be pleased with him) says: When we would stand for prayer, the Messenger of Allah (peace and blessings be upon him) would come to us and touch our shoulders or chests and say: Do not differ in this matter, otherwise your hearts will become opposed to one another. And he used to say: Indeed, Allah and His angels send mercy upon those in the first row.
