Where Did Prophet Adam Land on Earth?
Question

Is it true that Adam (peace be upon him) came down in India and that Hawwa’ came down in Jeddah?
Praise be to Allah.Where did Prophet Adam land on earth?
What is proven definitively in the Noble Quran is that Adam and Hawwa’ (peace be upon them) came down from Paradise to earth after they ate from the tree. 
Allah says (interpretation of the meaning):
“Then the Shaytan (Satan) made them slip therefrom (the Paradise), and got them out from that in which they were. We said: `Get you down, all, with enmity between yourselves. On earth will be a dwelling place for you and an enjoyment for a time.’” [Al-Baqarah 2:36]
With regard to the place where they came down on earth, the Quran does not say anything about it, and there is no authentic, marfu` hadith in the Sunnah of the Prophet (blessings and peace of Allah be upon him) which explains that, although there are some weak hadiths, such as the hadith that says: “Adam came down in India and felt lonely…”. This was narrated by Ibn `Asakir in Tarikh Dimashq (7/437) and classed as weak by Shaykh Al-Albani in As-Silsilah Ad-Da`ifah, no. 403. There are also other hadiths which speak of this matter, but their isnads are very weak. 
The only sahih reports about this matter are the words of some of the Salaf, most of which are taken from the knowledge of the people of the Book which were transmitted during their time. Such reports cannot be relied upon or trusted, and it is not permissible to believe in what they mention of things concerning which our religion is silent. Rather they may be narrated for the purpose of story-telling only. 
Scholarly opinions concerning where Prophet Adam landed on earth
Despite that, the scholarly opinions concerning this matter differ. 

Some of them said: Adam came down in India and Hawwa’ came down in Jeddah. 
Some of them said that they both came down in India. 
Some of them said that Adam came down in a land between Makkah and At-Ta’if called Dahna. 
Some of them said that Adam came down on As-Safa and Hawwa’ came down on Al-Marwah. 

Al-Hafiz Ibn Kathir (may Allah have mercy on him) said:  
“As-Suddi said: Allah said (interpretation of the meaning): “Get you down, all” [Al-Baqarah 2:36]. So they came down; Adam came down in India and the Black Stone and a handful of leaves from Paradise came down with him, and he scattered them in India, and a perfume tree grew, which is the origin of what comes from India of perfume from the handful of leaves that Adam brought down. Adam only took them because of his sorrow at leaving Paradise when he was expelled from it. 
`Imran ibn `Uyaynah said, (narrating) from `Ata’ ibn As-Sa`ib, from Sa`id ibn Jubayr, from Ibn `Abbas, who said: Adam came down from Paradise in Dahna, in the land of India.  
Ibn Abi Hatim said: Abu Zar`ah told us: Uthman ibn Abi Shaybah told us: Jarir told us: from `Ata’, from Sa`id, from Ibn `Abbas who said: Adam (peace be upon him) came down in a land called Dahna, between Makkah and At-Ta’if. 
It was narrated that al-Hasan Al-Basri said: Adam came down in India and Hawwa’ in Jeddah, and Iblis in Dastumisan a few miles from Basrah, and the serpent came down in Asbahan. This was narrated by Ibn Abi Hatim.  
Ibn Abi Hatim said: Muhamamd ibn `Ammar ibn Al-Harith told us: Muhammad ibn Sa`id ibn Sabiq told us: `Amr ibn Abi Qays told us, from Ibn `Adiyy, from Ibn `Umar, who said: Adam came down on As-Safa and Hawwa’ on Al-Marwah.” (Tafsir Al-Quran Al-`Azim, 1/237) 
But all of these are words for which there is no evidence. 
And Allah knows best.
