لِلَّذِينَ لَا يُؤْمِنُونَ بِٱلْءَاخِرَةِ مَثَلُ ٱلسَّوْءِ ۖ وَلِلَّهِ ٱلْمَثَلُ ٱلْأَعْلَىٰ ۚ وَهُوَ ٱلْعَزِيزُ ٱلْحَكِيمُ
For those who believe not in the Hereafter is an evil similitude, and Allah's is the Sublime Similitude. He is the Mighty, the Wise.
Surah An-Nahl(16:60)
Sahih al-Bukhari
Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))
"And (remember) when Ibrãhim (Abraham) and (his son) Isma'il (Ishmael) were raising the foundations of the House (Ka'bah at Makkah) (saying): 'Our Lord! Accept (this service) from us. Verily! You are the All-Hearer, the All-Knower'." (V.2:127)
Narrated `Aisha:
(The wife of the Prophet) Allah's Messenger (ﷺ) said, "Don't you see that when your people built the Ka`ba, they did not build it on all Abraham's foundations?" I said, "O Allah's Messenger (ﷺ)! Why don't you rebuild it on Abraham's foundations?" He said, "Were your people not so close to (the period of Heathenism, i.e. the Period between their being Muslims and being infidels), I would do so." The sub-narrator, `Abdullah bin `Umar said, "Aisha had surely heard Allah's Messenger (ﷺ) saying that, for I do not think that Allah's Messenger (ﷺ) left touching the two corners of the Ka`ba facing Al-Hijr except because the Ka`ba was not built on all Abraham's foundations."
