From where do pilgrims arriving from Sudan by sea and by air enter the state of ihram?

Question : This questioner says: Pilgrims and those performing 'Umrah coming from the lands of Sudan by sea have been accustomed to entering ihram from the city of Jeddah, and those coming by air have been accustomed to landing in Jeddah, then proceeding directly to al-Madinah, visiting the Prophet's Mosque, and staying there for days, then entering ihram from Abi 'Ali. Is this correct?

Answer : Yes, if the people of Africa from Sudan and other places intend to go to al-Madinah, and they land in Jeddah and go to al-Madinah and enter ihram from Abi 'Ali, then this is correct and there is no problem. However, if they do not intend to go to al-Madinah but rather intend to go to Makkah, then if they pass the miqat before reaching Jeddah, it is obligatory for them to enter ihram from the point where they pass the miqat. As for if it happens that they reach Jeddah before passing the miqats, such as the people of Suakin in Sudan and those who come via this route, then they enter ihram from Jeddah. Yes, there is no harm. If they came from the west, traveling directly to Jeddah, then they are not required to enter ihram except from Jeddah, meaning they remain in their clothes without the talbiyah and without anything else, and they enter ihram from Jeddah. However, if they are from northern Sudan or from Egypt.
Or if they are from southern Sudan, then they enter ihram when they pass the miqat, because those from the north pass Rabigh before they reach Jeddah, and those from the south pass Yalamlam, the miqat of the people of Yemen, before they reach Jeddah.
