Ikrimah said,

وَالْتَفَّتِ السَّاقُ بِالسَّاقِ

And one shank will be joined with another shank.

"The great matter (will be joined) with the great matter.''

Mujahid said, "A test (will be joined) with a test.''

Al-Hasan Al-Basri said concerning Allah's statement, وَالْتَفَّتِ السَّاقُ بِالسَّاقِ (And one shank will be joined with another shank).

"These are your two shins when they are bound together.''

In another narration from him (Al-Hasan) he said,

"His two legs have died and they will not carry him while he used to walk around on them.''

Concerning Allah's statement,

إِلَى رَبِّكَ يَوْمَئِذٍ الْمَسَاقُ ﴿٣٠﴾

The drive will be on that Day to your Lord!

meaning, the place of return and the destination. This is that the soul ascends into the heavens and Allah says,

"Return my servant to the earth, for verily, I have created them from it, I return them into it, and from it I will bring them out at another time.''

This has been reported in the lengthy Hadith of Al-Bara'.

Verily, Allah says,

وَهُوَ الْقَاهِرُ فَوْقَ عِبَادِهِ وَيُرْسِلُ عَلَيْكُم حَفَظَةً حَتَّى إِذَا جَآءَ أَحَدَكُمُ الْمَوْتُ تَوَفَّتْهُ رُسُلُنَا وَهُمْ لاَ يُفَرِّطُونَ

ثُمَّ رُدُّواْ إِلَى اللَّهِ مَوْلَـهُمُ الْحَقِّ أَلاَ لَهُ الْحُكْمُ وَهُوَ أَسْرَعُ الْحَـسِبِينَ

He is the Irresistible (Supreme), over His servants, and He sends guardians over you, until when death approaches one of you, Our messengers take his soul, and they never neglect their duty.

Then they are returned to Allah, their True Master. Surely, for Him is the judgement and He is the swiftest in taking account. (6:61,62)
