Surah: 2   Aya: 272

272. Laysa AAalayka hudahum walakinna Allaha yahdee man yashao wama tunfiqoo min khayrin fali-anfusikum wama tunfiqoona illa ibtighaa wajhi Allahi wama tunfiqoo min khayrin yuwaffa ilaykum waantum la tuthlamoona
  

  Translation

272. Not upon you (Muhammad SAW) is their guidance, but Allâh guides whom He wills. And whatever you spend in good, it is for yourselves, when you spend not except seeking Allâh's Countenance. And whatever you spend in good, it will be repaid to you in full, and you shall not be wronged.
