Tum mein se koi shaks jab apny Islam ko umdah bana le (yani nafaaq aur riya se paak ker le) to her naik kaam jo wo kerta ha uske aiwaz das (10) se le ker saat soo (700) guna tak naikyan likhi jati hein aur her bura kaam jo kerta ha to wo utna hi likha jata ha (jitna ke usne kya ha). [42: Volume 1; Sahee Bukhari Shareef] [Ravi: Hazrat Abu Hurairah]
