There is a consensus of scholastic opinion in this verse that Allah swore by the life span of Prophet Muhammad and means, "By your continuation, O Muhammad" and that it also bears the meaning, "By your life."
Kukhona ukuvumelana of imibono esikoleni kuleli vesi ngokuthi Allah wafunga isikhathi Prophet Muhammad futhi izindlela zokuphila, "By kuchubeka yakho, O Muhammad" nokuthi liphinde uthela nencazelo, "By ekuphileni kwakho."
