Ash-Sharh

A Discussion of Allah's Favor upon His Messenger Concerning Allah's statement,

﴿ وَوَضَعۡنَا عَنكَ وِزۡرَكَ ﴾

(And removed from you your burden.) This means

﴿ لِّيَغۡفِرَ لَكَ ٱللَّهُ مَا تَقَدَّمَ مِن ذَنۢبِكَ وَمَا تَأَخَّرَ ﴾

(That Allah may forgive you your sins of the past and the future.) (48:2)

﴿ ٱلَّذِىٓ أَنقَضَ ظَهۡرَكَ ﴾

(Which weighed down your back) Al-Inqad means the sound. And more than one of the Salaf has said concerning Allah's saying,

﴿ ٱلَّذِىٓ أَنقَضَ ظَهۡرَكَ ﴾

(Which weighed down your back) meaning, `its burden weighed heavy upon you.'
