he is important by his journeys
--------------------------------------------
Ibn Battuta is important because of the fact that he actually documented or recorded all of his travels. Wherever he went to and whatever civilizations he encountered, Ibn Battuta always documented his own feelings towards their customs and traditions, political and social setup. His recordings were all put into a book called the Rihla. What is important about this is that without his recordings there would have been many undiscovered civilizations. Historians would have never knew about these smaller civilizations without Ibn Battuta's book.
In the Qur'an, the name is simply "Zaid", with no additional names.We know from sources like Tabari that his full name was Zaid al-Habib ibn Harithah ibn Sharahil ibn Abduluzza ibn Imri al-Qays ibn Amir ibn Al-Numan ibn Amir ibn Abdwalid ibn Awf ibn Kinana ibn Awf ibn Uzra ibn Zaidallat ibn Rufayda ibn Thawt ibn Kalb ibn Wabara ibn Taghlib ibn Talwan ibn Irmram ibn Al-Haf ibn Quda'a ibn Malik ibn Amr ibn Murrah ibn Malik ibn Himayr ibn Saba ibn Yashjub ibn Yarab ibn Qaltan.Al-Habib ("the beloved") was a byname; Uzra was his clan; Kalb was his tribe proper; Taghlib was his super-tribe; Himayr was the general group of tribes in the area.So are you surprised that the Qur'an simply calls him "Zaid"?
