The very first and the most famous war of the believers in Islaam with the disbeliever infidels was the famous war of Badr fought by Muslims to defend Madina from being smashed by Makki pagan who came fully prepared wit-h all the necessary war arsenal. The Holy Prophet (Salallaho Alaihi Wasallam) commanded the Muslims and the enemy was engaged in the famous plain of Badr, some 80 miles away from Madina. Allah allowed the Muslims in 2nd Hijra to have defensive fight against the enemy as in Sura Al-Baqra 11:19. This is because Muslims defend their peaceful coexistence for Allah as in Sura Aale-Imraan 111:13 to remain grateful to Allah to establish His best, system as in Sura III :123. Allah made Muslims to look double to the enemy as in Sura III :13.

Sura Anfaal gives full account of the War of Badr being the greatest event of Islaarn and the turning point, in the History of islaam. Reference is made to Sura Anfaal VIII Verses 2 to 19, Verses 41 to 47, Verses 67 to 71.

The warning about the spoils of war of Badr snatched by successful Muslim warriers from the tally defeated infidels of Makkah has been revealed in Sura Anfaal VIII: 67 to 69 where principles have been laid down about the final phase of any defensive Muslim War. The Muslims who participate in Islaam Jahaad (sacred defensive and obligatory battles to maintain the march of truth of Allah for human co-existence, peace and prosperity have been laid down in scores of verses of the Holy Quraan. But the Sura Nisaa TV: 95 is comprehensive in brief on this subject. Sura XXII: 39 to 41 and Sura LI: 251 also prescribes to establish the system of Islaam with sincerity of purpose with integrity.

Sura Nisaa IV : 75 and Sura Anfaal VIII: 39 read with Sura Baqarah II :190 to achieve the objectives of Islaam by any sacrifice.

It was the holy month of Ramadhan-ull-Mubarak in the year of 2 Hijri that Aboo Jehl spread the rumour that their caravan, loaded with riches, was coming back to Makkah from Syria, and that Madina lies in the way. Muslims intend to plunder it. The purpose of this rumour was that all those people who had invested their capital in business, and also those whose relatives were in the caravan; and those who hate Muslims; they should get suspicious against Muslims; should unanimously get ready to wage a war against Muslims. Thus Aboo Jehl succeeded in his device to revenge the migration of Holy Prophet Salallaho Alaihi Wasallam and his followers, unhurt. The army of Quraysh comprised of one thousand spirited warriors which included seven hundred riders of camels and three hundred horses. Aboo Jehl marched forward leading this army. The trade caravan of Makkah which had obviously served as the cause of this military expedition of Makki infidels had travelled by another path to Makkah; yet Aboo Jehl continued advancing with this army towards Madina. Now it was clear for Muslims that protection of the caravan was only an excuse. This was only an invasion on the poor Muslims for no cause of concern from them on any account.

The Holy Prophet (blessings and salutations on him), consulted the companions (Allah is pleased with them) on this matter. The Mahajirs (emigrants) gave a satisfactory reply. The Ansaar leader Sa'ad Bin Ma-'aaz said, "Perhaps the Holy Prophets (blessings and salutations on him) thinks that the Ansars do not think it their duty to help you (Salallaho Alaihi Wasallam). We are under your (Salallaho Alaihi Wasallam) kind control and will. We shall obey as you order. The battle took place on Friday, the 17th of Ramadhan-ull-Mubarak when the Muslims were fasting despite of long journey. By help and support of Allah, the infidels were defeated. Seventy of their men were arrested. Aboo Jehl was killed by two Muslim youngsters along with several Makki chiefs.

According to war-rules of those days Hadhrat Omar R.A. along with many companions of the Holy Prophet Salallaho Alaihi Wasallam wanted to kill them for revenge and to over-awe the Makki invaders it was essential that all the persons who were arrested should have been murdered. But the Holy Prophet (blessings and salutations of Allah on him) as a blessing for the entire universe, set all of them free after taking ransom and deploying them on probation/parole to teach the illiterate boys, girls and elders of Madina.
