Waya qawmi istaghfiroo rabbakum thumma tooboo ilayhi yursili alssamaa AAalaykum midraran wayazidkum quwwatan ila quwwatikum wala tatawallaw mujrimeena
11:52 "And O my people! Ask forgiveness of your Lord, and turn to Him (in repentance): He will send you the skies pouring abundant rain, and add strength to your strength: so turn ye not back in sin!"
