Anas b Malik reported: Abu Talha sent me to Allah's Messenger ﷺ ; the rest of the hadith is the same, but 'there is a slight variation of wording that he said at the end (The Holy Prophet) took what was left (of the food) and collected it and then invoked blessings upon it and it returned to its original state. He (the Holy Prophet) then said Take this.
The Prophet Muhammad was an example of this teaching in action as he took the leftover food and blessed it before giving it away. He showed us how powerful blessings can be and how they can bring about positive change in our lives if we use them correctly. We should strive to follow his example by blessing our own meals before consuming them as well as blessing other people's meals when given the opportunity.
