عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((إِنَّ لِلْمَسَاجِدِ أَوْتَادًا، الْمَلَائِكَةُ جُلَسَاءُهُمْ إِنْ غَابُوا يَفْتَقِدُونَهُمْ، وَإِنْ مَرِضُوا عَادُوهُمْ، وَإِنْ كَانُوا فِي حَاجَةٍ أَعَانُوهُمْ)) وَقَالَ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((جَلِيسُ الْمَسْجِدِ عَلَى ثَلَاثِ خِصَالٍ، أَخٌ مُسْتَفَادٌ أَوْ كَلِمَةٌ مُحْكَمَةٌ أَوْ رَحْمَةٌ مُنْتَظَرَةٌ))
It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: Some people sit in the mosques like pegs; the angels are their companions. If they are absent, the angels search for them; if they are ill, the angels visit them; if they are occupied with some work, the angels assist them. And the Prophet, peace and blessings be upon him, said: The one who sits in the mosque is upon three qualities: a brother from whom benefit is gained, or a firm word, or such a mercy that is awaited.
