be upon him) said: “The Arabs are never exact at estimating people. They have never told me  about the virtues of a man correctly; for when I see the man concerned I realize that they have  overestimated him except Zaid Al-Khail, when I met him I knew that they had underestimated  him.” Then he named him ‘Zaid Al-Khair’ (i.e. Zaid, the bounteous).
The delegations arrived successively in Madinah during the ninth and tenth of Al-Hijra. Biographers  and  invasion-writers have written down about some of Yemen delegations. They were Al-Azd; Bani Sa‘d
Hadheem from Quda‘ah, Bani ‘Amir bin Qais; Bani Asad, Bahra’, Khaulan, Muharib, Bani Al-Harith bin
Ka‘b, Ghamid, Bani Al-Muntafiq, Salaman, Bani ‘Abs, Muzainah, Murad, Zabid, Kinda, Dhi Murrah,
Ghassan, Bani ‘Aish, and Nakh‘ which were the last group of delegates. Nakh‘ Delegation comprised  two  hundred men and they arrived in the middle of Muharram in the eleventh year of Al-Hijra. The  majority  of these groups of delegates arrived during the ninth and tenth years of Al-Hijra. The arrival of some  of  them tarried till the eleventh year of Al-Hijra.
The succession of these delegations indicated the great degree of the entire acceptance which the
Islamic Call reached. It manifested its influence and domination on vast areas of Arabia . The Arabs  observed Al-Madinah with such a great respect and estimation that they could do nothing but  surrender  and submit to it. Al-Madinah had become the headquarters of all Arabia; so it was impossible to avoid  it. We dare not say that all the Arabians were possessed and enchanted by this religion. There were  lots  of hard-hearted bedouins — among the Arabs — who surrendered (i.e. became Muslims) only because  their master did so. Their souls were not sanctified yet. Their tendency to raids had been deeply  rooted  in their souls. The teachings of Islam had not crystallized their souls well yet. Accounting some of  them  the Qur’ân says:
“The bedouins are the worst in disbelief and hypocrisy, and more likely to be in ignorance of the  limits (Allâh’s Commandments and His legal laws, etc.) which Allâh has revealed to His
Messenger. And Allâh is All-Knower, All-Wise. And of the bedouins there are some who look upon  what they spend (in Allâh’s cause) as a fine and watch for calamities for you, on them be the  calamity of evil. And Allâh is All-Hearer, All-Knower.” 9:97,98
The Qur’ân praised others saying:
“And of the bedouins there are some who believe in Allâh and the Last Day, and look upon what  they spend in Allâh’s cause as approaches to Allâh, and a cause of receiving the Messenger’s  invocations. Indeed these are an approach for them. Allâh will admit them to His Mercy. Certainly
Allâh is Oft-Forgiving, Most Merciful.” 9:99
Those of them who were present at Makkah, Madinah and Thaqif and in many other areas of Al-Yemen  and Al-Bahrain were different because Islam had been firmly rooted in their souls. Some of them were  great Companions and Masters of Muslims.
THE SUCCESS AND IMPACT OF THE CALL:
Before we move one more step and meditate on the last days of the Messenger of Allâh’s life, we  ought  to cast a quick glance at the great work that was a peculiarity of his. That very peculiarity that made  him excel all other Prophets and Messengers and made him so superb that Allâh made him atop the  formers and the latters. It was him that was addressed by:
“O you wrapped in garments i.e Prophet Muhammad (Peace be upon him)! Stand (to pray) all  night, except a little.” 73:1,2
And said:
“O you Muhammad (Peace be upon him) enveloped (in garments). Arise and warn!” 74:1,2
So he arose and kept on like that for over twenty years. During those years he undertook to carry the  burdens of the great expectations on his shoulders for the sake of the whole mankind and humanity,  the Faith and Jihad in various fields.
The Messenger of Allâh (Peace be upon him) undertook the burdens of struggle and Al-Jihad in the  conscience of mankind which was then drowning in the illusions of Al-Jahiliyah and its images that  were  loaded with the ground weights and gravitations. He took upon his shoulder to free man’s conscience
