The ruling on stoning the pillars before the sun reaches its zenith on the thirteenth day

Question:
The third question says: If we find it difficult to wait for the sun to reach its zenith, which is the time for stoning the pillars on the thirteenth day, is it permissible for us to stone the pillars before the zenith? Is there a difference of opinion among the schools of jurisprudence on this?

Answer:
It is not permissible for a Muslim to throw the stones before the sun passes its zenith. Rather, on the twelfth and thirteenth days, just as on the eleventh day, he must throw the stones after the sun passes its zenith, and he must not transgress by throwing before the zenith.
There is a difference of opinion on this matter. Some scholars hold that there is no harm in advancing the throwing on the day of departure, but not every difference of opinion is considered valid; rather, only a difference of opinion that has a share of validity is considered. There is no valid difference of opinion here, because this difference of opinion contradicts the Sunnah. The Prophet (peace and blessings be upon him) threw the stones after the sun passed its zenith, even on the thirteenth day. He did not descend from Mina until after he had thrown the stones after the zenith, then he descended and stayed in al-Abtah for the Dhuhr prayer and ten minutes. So do not leave Mina; do not throw the stones except after the sun passes its zenith, even on the day of departure.
