Arabic (Original)
وَقَالَ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ جَلِيسُ الْمَسْجِدِ عَلَى ثَلَاثِ خِصَالٍ أَخٍ مُسْتَفَادٍ أَوْ كَلِمَةٍ مُحْكَمَةٍ أَوْ رَحْمَةٍ مُنْتَظَرَةٍ.
English Translation
And he (peace and blessings of Allah be upon him) said: "The one who sits in the mosque is upon three qualities: a brother he benefits from, a word of wisdom, or a mercy he awaits."
