Surah Fatir Tafseer

إِنَّ اللَّهَ يُمْسِكُ السَّمَاوَاتِ وَالاَْرْضَ أَن تَزُولَا

Verily, Allah grasps the heavens and the earth lest they should move away from their places,

means, lest they should shift from where they are.

This is like the Ayat:

وَيُمْسِكُ السَّمَأءَ أَن تَقَعَ عَلَى الاٌّرْضِ إِلاَّ بِإِذْنِهِ

He withholds the heaven from falling on the earth except by His leave. (22:65)

and,

وَمِنْ ءَايَـتِهِ أَن تَقُومَ السَّمَأءُ وَالاٌّرْضُ بِأَمْرِهِ

And among His signs is that the heaven and the earth stand by His command. (30:25)

وَلَيِن زَالَتَا إِنْ أَمْسَكَهُمَا مِنْ أَحَدٍ مِّن بَعْدِهِ

and if they were to move away from their places, there is not one that could grasp them after Him.

means, no one can make them stay and preserve them except Him.

He is Ever Most Forbearing and Oft-Forgiving because He sees His servants disbelieving in Him and disobeying Him, yet He is patient and gives them time, He waits and does not hasten the punishment, and He conceals the faults of others and forgives them.

He says:

إِنَّهُ كَانَ حَلِيمًا غَفُورًا

Truly, He is Ever Most Forbearing, Oft-Forgiving
