Oh prisoners of hope;
even now I announce
I will restore twice as much to you.
~ Zechariah 9
Allah's Apostle said,Tomorrow I will give the flag to a man with whose leadership Allah will grant (the Muslim) victory. So the people kept on thinking the whole night as to who would be given the flag. The next morning the people went to Allah's Apostle and every one of them hoped that he would be given the flag. The Prophet said, Where is Ali bin Abi Talib? The people replied, He is suffering from eye trouble, O Allah's Apostle. He said, Send for him and bring him to me. So when 'Ali came, the Prophet spat in his eyes and invoked good on him, and he became alright as if he had no ailment. The Prophet then gave him the flag. 'Ali said, O Allah's Apostle! Shall I fight them i.e. enemy till they become like us? The Prophet said, Proceed to them steadily till you approach near to them and then invite them to Islam and inform them of their duties towards Allah which Islam prescribes for them, for by Allah, if one man is guided on the right path i.e. converted to Islam) through you, it would be better for you than a great number of red camels.
This hadith is in Sehih Bukhari, volume 5, book 57, hadith number 51.
Allah's Apostle said, "The reward of deeds depends upon the intention and every person will get the reward according to what he has intended. So whoever emigrated for Allah and His Apostle, then his emigration was for Allah and His Apostle. And whoever emigrated for worldly benefits or for a woman to marry, his emigration was for what he emigrated for."
here is the text for ch 5:51
O YOU who have attained to faith! Do not take the Jews and the Christians for your allies: they are but allies of one another and whoever of you allies himself with them becomes, verily, one of them; behold, God does not guide people who are unjust.
Befriending Christians and Jews
