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.'
