He became Muslim at the time of prayer; should he make up what came before it?

If a person becomes Muslim at the time of prayer, does he have to make
up what came before it?.
Praise be to Allaah.
He does not have to makeup what came before it, because Allaah says
(interpretation of the meaning):
"Say to those who have disbelieved, if they cease (from disbelief),
their past will be forgiven"
[al-Anfaal 8:38].
i.e., if they give up their kufr and become Muslim, then Allaah will
forgive them their previous sins, whether these were sins of
neglecting obligatory duties or doing haraam acts. But he must offer
theprayer at the time of which he became Muslim, if there remained
enough time to do one rak'ah or more, because the Prophet (peace and
blessings of Allaah be upon him) said: "Whoevercatches up with a
rak'ah of the prayer has caught up with the prayer."
As for the prayers that came before, he does not have to make them up,
such as if he became Muslim after 'Asr, he has to make up 'Asr, but he
does not have to make upZuhr, because the time forit had ended.
