حَدَّثَنَا هَارُونُ بْنُ مَعْرُوفٍ، حَدَّثَنَا ابْنُ وَهْبٍ، عَنْ عَمْرِو بْنِ الْحَارِثِ، أَنَّ أَبَا عُشَّانَةَ الْمَعَافِرِيَّ، حَدَّثَهُ عَنْ عُقْبَةَ بْنِ عَامِرٍ، قَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏"‏ يَعْجَبُ رَبُّكُمْ مِنْ رَاعِي غَنَمٍ فِي رَأْسِ شَظِيَّةٍ بِجَبَلٍ يُؤَذِّنُ بِالصَّلاَةِ وَيُصَلِّي فَيَقُولُ اللَّهُ عَزَّ وَجَلَّ انْظُرُوا إِلَى عَبْدِي هَذَا يُؤَذِّنُ وَيُقِيمُ الصَّلاَةَ يَخَافُ مِنِّي فَقَدْ غَفَرْتُ لِعَبْدِي وَأَدْخَلْتُهُ الْجَنَّةَ ‏"‏ ‏.‏

Narrated Uqbah ibn Amir: I heard the Messenger of Allah (PBUH) say: Allah is pleased with a shepherd of goats who calls to prayer at the peak of a mountain, and offers prayer, Allah, the Exalted, says: Look at this servant of Mine; he calls to prayer and offers it and he fears Me. So I forgive him and admit him to paradise. Translation Not Available
