Regarding its emphatic significance (and our attitude towards it), a man came to ‘Abd-Allah ibn Mas’ood رضي الله عنه and asked him for advise. He replied:
“When you hear Allah Say: ‘O you who have believed’, concentrate your hearing towards it – for it contains goodness that is ordered (to be performed), or evil that is forbidden (and must be avoided).” [Ibn Abi Hatim (as related by Ibn Katheer in his Tafseer)]
Shaykh Abu Bakr al-Jaza’iri gathered all instances of this phrase in his superb book entitled ‘Nida’at Ar-Rahman li ahl al-Imaan‘ (Call of Ar-Rahman to His believing slaves) and provided an concise explanation for each one. In its introduction, he explains that the Order of Allah in these Ayaat contain critical details that teach the believers what will benefit them and what will cause them harm. This is something that should be known by every Muslim in order to attain happiness in this world and success in the Hereafter. It covers issues surrounding aqeedah, ibadah, akhlaq, mu’amalaat, law and so on.
Allah is the Source of Guidance.
