وعن معاذ بن أنس رضى الله عنه
قال: قال رسول الله صلى الله عليه وسلم: «من أكل طعاماً فقال: الحمد الله الذي أطعمني هذا، ورزقنيه من غير حول منى ولا قوةٍ، غفر له ما تقدم من ذنبه»
Messenger of Allah (sallallahu alayhi wa sallam) said, “He who has taken food and says at the end: ‘Al- hamdu lillahi-lladhi atamani hadha, wa razaqanihi min ghairi haulin minni wa la quwwatin (All praise is due to Allah Who has given me food to eat and provided it without any endeavour on my part or any power),’ all his past sins will be forgiven.”.
