Hadith.1538 - It is narrated from Ali ibn al-Rayan that He said: I wrote to the Last Imam (as) asking about a man who prayed two rak'ahs of the Salat of Ja'far but was forced to interrupt before completing the final two rak'ahs due to a need or an event that occurred. Would it be permissible for him to complete the remaining rak'ahs once his need was met, even if he had left his original place of prayer, or must he start the prayer again and pray all four rak'ahs together without interruption? He (as) replied: "Yes, if he was interrupted by a matter of necessity, then let him stop and afterward return to complete what remains, if Allah (swt) wills."

If you wish, you may count it as part of the supererogatory prayers of the night, and if you wish, you may count it as part of the supererogatory prayers of the day. It will be counted as part of your supererogatory prayers and as the Salat of Ja'far (as)."
