عَنْ مُعَاذِ بْنِ أَنَسٍ الْجُهَنِيِّ صَاحِبِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ مَنْ قَرَأَ {قُلْ هُوَ اللَّهُ أَحَدٌ} [الإخلاص: 1] حَتَّى يَخْتِمَهَا عَشْرَ مَرَّاتٍ بَنَى اللَّهُ لَهُ قَصْرًا فِي الْجَنَّةِ فَقَالَ عُمَرُ بْنُ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُ إِذَنْ أَسْتَكْثِرَ يَا رَسُولَ اللَّهِ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ اللَّهُ أَكْثَرُ وَأَطْيَبُ
Narrated by Sayyiduna Mu'adh bin Anas al-Juhani, may Allah be pleased with him: The Noble Prophet, peace and blessings be upon him, said: Whoever recites {قُلْ ھُوَ اللّٰہُ اَحَدٌ}, that is, Surah Al-Ikhlas, to the end ten times, Allah Almighty will build a palace for him in Paradise. Sayyiduna Umar, may Allah be pleased with him, said: O Messenger of Allah! Then I can have many palaces. The Prophet, peace and blessings be upon him, said: Allah Almighty is even more abundant and the bestower of excellent gifts.
