Ruling on one who fasts on the Day of 'Arafah and then arrives for Hajj before sunset

Question:
Last year, I was fasting on the Day of 'Arafah, and suddenly I resolved to attend the standing at 'Arafah, which was a short time before sunset, due to the short distance between Makkah and 'Arafah. I broke my fast at 'Arafah with the sunset while I was in the state of ihram at that moment. What is your opinion on this, regarding fasting, standing at 'Arafah, and being in ihram all at the same time?

Answer:
There is no blame on you. Whenever you arrive at 'Arafah at night, the Hajj is valid, as the Prophet (peace and blessings be upon him) said: . If one arrives before sunset, that is more complete and more perfect. If one arrives before sunset and the sun sets on him, he has caught the Hajj, whether fasting or not. However, it is prescribed for pilgrims not to fast; it is a recommended practice (sunnah) for the pilgrim not to fast on the Day of 'Arafah, but rather to be not fasting. The Prophet (peace and blessings be upon him) stood at 'Arafah while not fasting.
The recommended practice (sunnah) for you, O believer, is to arrive at 'Arafah after the sun has passed its zenith, and to pray the Dhuhr and 'Asr prayers there. Do not stay in your house until you arrive before sunset. Rather, the better and more perfect course is to arrive at Mina on the eighth day, and to pray the Dhuhr, 'Asr, Maghrib, 'Isha', and Fajr prayers there. Then, head to 'Arafah on the morning of the Day of 'Arafah while not fasting. This is the recommended practice (sunnah).
As for the one who came: he fasted in Makkah, arrived at 'Arafah before sunset, broke his fast there, and completed the Hajj; his Hajj is valid, but he missed a great virtue. He missed standing at the beginning of the time, and he missed the Fajr prayer at 'Arafah, and the Dhuhr and 'Asr prayers. He missed arriving at Mina on the eighth day, and he missed... traveling from Mina to 'Arafah in the morning. He missed great virtues and recommended practices (sunnan).
