وَٱتَّخَذَ قَوْمُ مُوسَىٰ مِنۢ بَعْدِهِۦ مِنْ حُلِيِّهِمْ عِجْلًۭا جَسَدًۭا لَّهُۥ خُوَارٌ ۚ أَلَمْ يَرَوْا۟ أَنَّهُۥ لَا يُكَلِّمُهُمْ وَلَا يَهْدِيهِمْ سَبِيلًا ۘ ٱتَّخَذُوهُ وَكَانُوا۟ ظَٰلِمِينَ
And the folk of Moses, after (he left them), chose a calf (for worship), (made) out of their ornaments, of saffron hue, which gave a lowing sound. Saw they not that it spake not unto them nor guided them to any way? They chose it, and became wrong-doers.

Chapter: The construction of (the prophet's pbuh) mosque
Narrated `Abdullah bin `Umar:
In the lifetime of Allah's Messenger (ﷺ) the mosque was built of adobes, its roof of the leaves of date-palms and its pillars of the stems of date-palms. Abu Bakr did not alter it. `Umar expanded it on the same pattern as it was in the lifetime of Allah's Messenger (ﷺ) by using adobes, leaves of date-palms and changing the pillars into wooden ones. `Uthman changed it by expanding it to a great extent and built its walls with engraved stones and lime and made its pillars of engraved stones and its roof of teak wood.
