The Matter of Guidance and other than it is in the Hand of Allah, and Allah's Warning about the Hell

Qatadah said,

إِنَّ عَلَيْنَا لَلْهُدَى

وَمَا لِأَحَدٍ عِندَهُ مِن نِّعْمَةٍ تُجْزَىٰ (while no one has conferred any favour on him for which he would give a return,...92:19) Sayyidna Abu Bakr ؓ did this great favour by spending abundant wealth. The emancipated slaves had not done him any favour in the past, so that one could say that he was returning their favour. He took this step for one purpose only as the verse says:

إِلَّا ابْتِغَاءَ وَجْهِ رَ‌بِّهِ الْأَعْلَىٰ (but [ he gave his wealth in charity ] only to seek the Countenance of his Lord, the Most High....92:20). Mustadrak of Hakim records that it was a usual practice of Sayyidna Abu Bakr that he used to purchase Muslim slaves from the disbelievers and set them free whenever he found them in their bondage. Generally, these people were weak and helpless. Abu Qahafah ؓ ، the father of Abu Bakr ؓ ، said to him: "Since you are emancipating slaves, why do you not set free strong and brave people, so that they may assist you in fighting the enemies and protect you." He replied: "My purpose of emancipating them is not to expect any benefit in return. My only purpose is to seek the pleasure of Allah." [ Mazhari ]
