I heard the Messenger of Allah ﷺ 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.  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ يَعْجَبُ رَبُّكُمْ مِنْ رَاعِي غَنَمٍ فِي رَأْسِ شَظِيَّةٍ بِجَبَلٍ يُؤَذِّنُ بِالصَّلاَةِ وَيُصَلِّي فَيَقُولُ اللَّهُ ﷻ انْظُرُوا إِلَى عَبْدِي هَذَا يُؤَذِّنُ وَيُقِيمُ الصَّلاَةَ يَخَافُ مِنِّي فَقَدْ غَفَرْتُ لِعَبْدِي وَأَدْخَلْتُهُ الْجَنَّةَ
