عَنْ أَبِي أُمَامَةَ، عَنِ النَّبِيِّ صَلَّى الله عَلَيْهِ وَسَلَّمْ قَالَ: «مَنْ غَدَا إِلَى الْمَسْجِدِ لَا يُرِيدُ إِلَّا أَنْ يَتَعَلَّمَ خَيْرًا أَوْ يَعْلَمَهُ، كَانَ لَهُ كَأَجْرِ حَاجٍّ تَامًّا حِجَّتُهُ» হযরত উমামা রাঃ হতে বর্ণিত। The Prophet (peace and blessings of Allaah be upon him) said: Whoever goes to the mosque just to teach or to teach, his reward is like that of a pilgrim whose Hajj has been completed.
