Imaam Shaafi’ (Rahmatullahi alaih) said: “It is more virtuous to seek Ilm-e-Deen [Knowledge of the Deen] than to engage in Nafl Salaat.” What this means is that priorities should be in order. Study Ilm-e-Deen and perfect your Amal with the knowledge you have learnt. The above statement does not mean that one should abandon Nawaafil. It simply means that the Nawaafil offered with correct Ilm of the requisite Masaail, is superior, very much superior than engaging in Salaat without observing the Sunnah method of Salaat.
