584 - وَ سُئِلَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: عَنِ اَلْمَصْلُوبِ يُصِيبُهُ عَذَابُ اَلْقَبْرِ فَقَالَ «إِنَّ رَبَّ اَلْأَرْضِ هُوَ رَبُّ اَلْهَوَاءِ فَيُوحِي اَللَّهُ عَزَّ وَ جَلَّ إِلَى اَلْهَوَاءِ فَيَضْغَطُهُ أَشَدَّ مِنْ ضَغْطَةِ اَلْقَبْرِ.
Hadith.584 - Imam Jafar ibn Muhammad Al-Sadiq 
was asked about the one who is crucified (and thus does not have a burial in the ground) and whether they are subject to the punishment of the grave.
Imam said: "Indeed, the Lord (azj) of the earth is the Lord (azj) of the air, and Allah (swt), the Mighty and Majestic, commands the air to press upon him more intensely than the squeezing of the grave."
