Allah says,
[أَلَمْ نَشْرَحْ
لَكَ صَدْرَكَ ]
(Have We not opened your breast for you) meaning, `have We not opened your
chest for you.' This means, `We illuminated it, and We made it spacious, vast
and wide.' This is as Allah says,
[فَمَن يُرِدِ
اللَّهُ أَن يَهْدِيَهُ يَشْرَحْ صَدْرَهُ لِلإِسْلَـمِ]
(And whomsoever Allah wills to guide, He opens his breast to Islam.) (6:125)
And just as Allah expanded his chest, He also made His Law vast, wide,
accommodating and easy, containing no difficulty, hardship or burden.
