When we have the opportunity to do overtime at work and earn time and a half or double pay, we ensure we do not miss out on the opportunity.
In Ramadhān, a fardh (compulsory) action is worth seventy times its value and a nafl (optional) action is worth the same as a fardh action out of Ramadhān. Despite the increase in rewards being so huge, we do not find the zeal to do anything extra for our hereafter, in stark contrast to our readiness to do overtime for material gain.
