He hastened to leave Mina then he found out that he had made a mistake in stoning the Jamaraat, so he went back and stoned them at night; is he still regarded as having hastened?

If this man hastened to leave and he
departed from Mina before the sun set, then he found out that there had been
a mistake in his stoning of the Jamaraat, so he went back to make it up,
then he can do the stoning then leave Mina, because this stoning is to make
up for something he had missed out on. Allah, may He be glorified and
exalted, says (interpretation of the meaning): “And remember Allah during
the appointed Days. But whosoever hastens to leave in two days, there is no
sin on him and whosoever stays on, there is no sin on him, if his aim is to
do good and obey Allah (fear Him), and know that you will surely be gathered
unto Him” [al-Baqarah 2:203]. 

But if he delayed stoning on the twelfth
until night, then he must remain and spend that night in Mina, then stone
the Jamaraat again on the thirteenth. End quote.
