﴿ ثُمَّ كَانَ مِنَ ٱلَّذِينَ ءَامَنُوا۟ وَتَوَاصَوْا۟ بِٱلصَّبْرِ وَتَوَاصَوْا۟ بِٱلْمَرْحَمَةِ ﴾

“and being, withal, of those who have attained to faith, and who enjoin upon one another patience in adversity, and enjoin upon one another compassion.”

while being thumma kāna is a supplement to iqtahama ‘he assaulted’; thumma is for the ordering of things to be mentioned in other words what is meant is that at the point of the assault he was one of those who believe and enjoin one another to steadfastness in pursuing obedience and in refraining from disobedience and enjoin one another to compassion marhama means rahma towards creatures.
