And from him, from Muhammad ibn Miskin, from Mu’awiyah ibn ‘Ammar, from Najiyyah, who said: I said to Abu Ja’far عليه السلام: "The time of the prayer reaches me or enters while I have not yet prayed, should I begin with the ‘nafilah’ (supererogatory prayer)?" Abu Ja’far عليه السلام said: "No. Rather, begin with the obligatory prayer (‘al-maktubah’), and make up the ‘nafilah’ afterward."
