Say (O Muhammad SAW): “Verily, my Salat (prayer), my sacrifice, my living, and my dying are for Allah, the Lord of the ‘Alamin (mankind, jinns and all that exists).
The following excerpt is taken from “Maariful Quran” under the commentary of Surah 6 Verse 162 pg. 529-530:
In the third verse, it was said:
(Say, “My prayer, my offering, my life and my death are all for Allah, the Lord of all the worlds).
The word: (nusuk) in this verse means sacrifice. Everything one does in Hajj is also called: Nusuk. So, the rites of Hajj are known as Mansik, the plural of Nusuk. Then, this word is also used for ‘Ibadah or worship of Allah in the absolute sense. Therefore, Nasik is used in the sense of ‘Abid (one who worships Allah). At this place, any of the meanings given above can be applied. Tafsirs to that effect have been reported from commentators among the $ahabah and Tabeen. But, ‘Ibadah or offering of acts of worship devoted to Allah, taken in the absolute sense, appears to be the more appropriate meaning at this place. In that case, the meaning of the verse would be: ‘My prayer, my offerings in ‘Ibgdah, my life and my death are all for Allah, the Lord of all the worlds.’
Out of the subsidiaries of deeds, the first to be mentioned here was Salah because that is the moving spirit of all good deeds and is, of course, the pillar of the religion. Mentioned briefly after that were all deeds and acts of worship. Then, rising to a wider level, everything done or faced in a lifetime was pointed to. The last to be mentioned was death. After having identified all these, it was admitted that they are only for Allah who is the Lord of all the worlds and who has no associate or partner in His Divinity. And this is the outcome of perfect faith and perfect sincerity. This leads one to think, care and keep in sight, in all states of life and in everything one does, that: ‘my Rabb, and the Rabb of the whole wide world is One Rabb. I am His servant. I am in His sight – all the time. Let not my heart, my mind, my eyes, my ears, my tongue, and hands, and feet, nor my pen or step, move in any direction against His pleasure.’ This is a simple meditation (Muraqabah) of the highest order, something which, if one trains himself to keep present in one’s heart and mind, then, there is no doubt that he or she will become a human being in the real sense. Things like sin and disobedience and crimes will be scared to come anywhere even close to a person that strong.
