وَعَنِ ابْنِ عُمَرَ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «إِنَّ الرُّكْنَ وَالْمَقَامَ يَاقُوتَتَانِ مِنْ يَاقُوتِ الْجَنَّةِ طَمَسَ اللَّهُ نورَهما وَلَو لم يطمِسْ نورَهما لأضاءا مَا بينَ المشرقِ والمغربِ» . رَوَاهُ التِّرْمِذِيّ

Ibn ‘Umar said that he heard God's messenger say, “The Corner and the Station are two of the sapphires of paradise whose light God has obliterated. If He had not done so, they would have illuminated everything between the East and West." Tirmidhi transmitted it.
