O you who believe, fear Allah and speak words of truth. He will rectify your deeds and forgive

The Shaykh : As for what follows: The best of speech is the speech of Allah, and the best of guidance is the guidance of Muhammad (peace and blessings be upon him). The worst of matters are those that are newly invented, and every newly invented matter is a religious innovation, and every religious innovation is misguidance, and every misguidance is in the Fire. We are still in chapters, all of which are about mercy. Now, the author says in the chapter seventy-five after the hundred: "The Chapter on Mercy Toward Children." This is like a section or part of some of the previous chapters, the last of which was "The Chapter on Having Mercy on Those on Earth." As we mentioned in the previous lesson, "those on earth" includes humans in both their categories, the believer and the disbeliever, and it also includes animals. Now, the author establishes a chapter that is a branch of that chapter and a section of it, in which he cites, with his authentic chain of narration, from Anas ibn Malik (may Allah be pleased with him), who said: "The Prophet (peace and blessings be upon him) was the most merciful of people toward children." Children, as is well known, means the family. "The Prophet (peace and blessings be upon him) was the most merciful of people toward children, and he had a son who was being breastfed in a part of Medina, and his wet nurse was a blacksmith, and we would come to him, and the house would be filled with smoke from burning tamarisk; he would kiss him and smell him."
This is the text of the hadith.
