Performing Hajj but standing at 'Arafah for only one hour due to being occupied: Is his Hajj valid?

Question : The questioner did not mention his name in this message. He says: I hope the Honorable Shaykh will clarify the answer to this question. I performed Hajj with one of the Hajj groups, and because I was the person in charge, I was occupied on the Day of 'Arafah searching for the lost bus. I was not able to stand at 'Arafah until after 'Asr, for about half an hour, and after Maghrib, for about half an hour. What is the ruling on my Hajj? May Allah reward you.

Answer : This questioner's Hajj is valid, and his occupation with the needs of his brothers is something for which he will be rewarded.
