Narrated Abu Salama: That there was a dispute between him and some people (about a piece of land). When he told `Aisha about it, she said, "O Abu Salama! Avoid taking the land unjustly, for the Prophet said, 'Whoever usurps even one span of the land of somebody, his neck will be encircled with it down the seven earths."

Hadith Commentary: Since there are seven layers of the earth, therefore, land acquired through oppression will be made into a collar and placed around his neck, extending through all seven layers. The seven layers of the earth are established from the Book and the Sunnah. Whoever denies them is a denier of the Qur’an and Hadith. The details of this are known to Allah. ﴿وَمَايَعْلَمُجُنُودَرَبِّكَإِلَّاهُوَ﴾ ( al-Muddathir: 31) Imam Shawkani rahimahullah states: “And in it is that the seven earths are layers like the heavens, and this is apparent from His, the Exalted’s, statement: ‘and from the earth the like thereof’ in opposition to those who say that by ‘seven earths’ is meant seven regions.” ( Nayl) That is, from this it is established that just as there are seven heavens, there are also seven layers of the earth, as mentioned in the Qur’anic verse ‘and from the earth the like thereof’, meaning the earths are also like those heavens. In this is also a refutation of those who interpret the seven earths as seven regions, which is not correct.

Ibn 'Umar reported that the Messenger of Allah (ﷺ) used to say prayer on his camel while coming from Makkah to Madinah, in whatever direction his face had turned; and its was (in this context) that this verse was revealed: "So whether you turn thither is Allah's face" (ii. 115).

Hadith Commentary:Benefits and Issues: Supererogatory (nafl) prayers can be performed on any type of mount, and there is no difference of opinion among the four Imams regarding this. Evidence for this is also found in the Qur’anic verse. However, at the beginning, if it is possible for the mount to face the qiblah, it is better; afterwards, its direction may be towards any side. And the blessed verse: ﴿فَأَيْنَمَاتُوَلُّوافَثَمَّوَجْهُاللَّهِ﴾ is related to supererogatory prayer during travel, that a person may perform nafl prayer on a mount while traveling. There is no need to dismount from the ride.
