﴿وَوَضَعْنَا عَنكَ وِزْرَكَ ﴾

(And removed from you your burden.) This means

﴿لِّيَغْفِرَ لَكَ اللَّهُ مَا تَقَدَّمَ مِن ذَنبِكَ وَمَا تَأَخَّرَ﴾

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

﴿الَّذِى أَنقَضَ ظَهْرَكَ ﴾

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

﴿الَّذِى أَنقَضَ ظَهْرَكَ ﴾

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