and Allah said "And proclaim the pilgramage among men; they will come to thee on foot and on every kind of camel. Lean on account of Journeys through deep and distant mountain highways" Surah 22 ~ Al Hajj Part 27
Narrated by Aisha Bint Abu Bakr (the wife of the Prophet): "I never remembered my parents believing in any religion other than the true religion (Islam), and (I don't remember) a single day passing without our being visited by Allah's Messenger in the morning and in the evening. When the Muslims were put to test (troubled by the pagans), Abu Bakr set out migrating to the land of Abyssinia (Ethiopia), and when he reached Bark-al-Ghimad, Ibn Ad-Daghina, the chief of the tribe of Qara, met him and said, 'O Abu Bakr! Where are you going?' Abu Bakr replied: 'My people have turned me out (of my country), so I want to wander on the earth and worship my Lord.' Ibn Ad-Dhagina said: 'O Abu Bakr! A man like you should not leave his homeland, nor should he be driven out, because you help the destitute, earn their living, and you keep good relations with your kith and kin, help the weak and the poor, entertain guests generously, and help the calamity-stricken persons. Therefore, I am your protector. Go back and worship your Lord in your town.'
"So Abu Bakr returned and Ibn Ad-Daghina accompanied him. In the evening Ibn Ad-Dhagina visited the nobles of Quraish and said to them. 'A man like Abu Bakr should not leave his homeland, nor should he be driven out. Do you (Quraish) drive out a man who helps the destitute, earns their living, keeps good relations with his kith and kin, helps the weak and poor, entertain guests generously and helps the calamity-stricken persons?' So the people of Quraish could not refuse Ibn Ad-Dhagina's protection, and they said to Ibn Ad-Daghina: 'Let Abu Bakr worship his Lord in his house. He can pray and recite there whatever he likes, but he should not hurt us with it, and should not do it publicly, because we are afraid that he may affect our women and children." Ibn Ad-Dhagina told Abu Bakr all of that. Abu Bakr stayed in that state, worshipping his Lord in his house. He did not pray publicly, nor did he recite Quran outside his house.
"Then a thought occurred to Abu Bakr to build a mosque in front of his house, and there he used to pray and recite the Quran. The women and children of the pagans began to gather around him in great number. They used to wonder at him and look at him. Abu Bakr was a man who used to weep too much, and he could not help weeping or reciting the Quran. That situation scared the nobles of the pagans of Quraish, so they sent for Ibn Ad-Daghina. When he came to them, they said: 'We accepted your protection of Abu Bakr on condition that he should worship his Lord in his house, but he has violated the conditions and he has built a mosque in front of his house where he prays and recites the Quran publicly. We are afraid that he may affect our women and children unfavorably. So, prevent him from that. If he likes to confine the worship of his Lord to his house, he may do so, but if he insists on doing that openly, ask him to release you from your obligation to protect him, for we dislike to break our pact with you, but we deny Abu Bakr the right to announce his act publicly.' Ibn Ad-Dhagina went to Abu Bakr and said: 'O Abu Bakr! You know well what contract I have made on your behalf; now, you are either to abide by it, or else release me from my obligation of protecting you, because I do not want the Arabs hear that my people have dishonored a contract I have made on behalf of another man.' Abu Bakr replied: 'I release you from your pact to protect me and am pleased with the protection from Allah.' Aisha's narration's continues: "At that time the Prophet was in Mecca (Makkah), and he said to the Muslims: 'In a dream I have been shown your migration place, a land of date palm trees, between two mountains, the two stony tracts.' So, some people migrated to Yatrib , and most of those people who had previously migrated to the land of Ethiopia , returned to Yatrib . Abu Bakr also prepared to leave for Yatrib , but Allah's Messenger said to him: 'Wait for awhile, because I hope that I will be allowed to migrate also.' Abu Bakr replied: 'Do you indeed expect this? Let my father be sacrificed for you!' The Prophet said: 'Yes.' So Abu Bakr did not migrate for the sake of Allah's Messenger in order to accompany him. He fed two she camels he possessed with the leaves of As-Samur tree that fell on being struck by a stick for four months.
"One day, while we were sitting in Abu Bakr's house at noon, someone said to Abu Bakr: 'This is Allah's Messenger with his head covered coming at a time at which he never used to visit us before.' Abu Bakr said: 'May my parents be sacrificed for him. By Allah he has not come at this hour except for a great necessity.' So Allah's Messenger came and asked permission to enter, and he was allowed to enter. When he entered, he said to Abu Bakr: "Tell everyone who is present with you to go away.' Abu Bakr replied: 'There are none but your family, May my father be sacrificed for you, O Allah's Messenger!' The Prophet said: 'I have been given permission to migrate.' Abu Bakr said: 'Shall I accompany you? May my father be sacrificed for you, O Allah's Messenger!' Allah's Messenger said: 'Yes.' Abu Bakr said, 'O Allah's Messenger! May my father be sacrificed for you, take one of these two she-camels of mine.' Allah's Messenger replied: 'I will accept it with payment.' So we prepared the baggage quickly and put some journey food in a leather bag for them. Asma, Abu Bakr's daughter, cut a piece from her waist belt and tied the mouth of the leather bag with it, and for that reason she was named 'Dhat-un-Nitaqain' (the owner of two belts).
