TALUT, JALUT AND DAUD

"Their (children of Israel) Prophet told them, "Allah has appointed Talut (Saul) as your king."  They replied, "How can he be our king when some of us are more deserving then he? Besides he is not rich." The Prophet said, "Allah has chosen him to rule over you and has blessed him with more knowledge and a bigger stature.  Allah grants kingship to whom He pleases and Allah is All-Sufficient for His creature's needs and All-Knowing." Furthermore, their Prophet told them, "The sign of his appointment as a king is that there will come to you the chest in which there is tranquility from your Rabb, the residue of relics which the family of Musa and the family of Haroon (Aaron) left behind, and that chest will be carried by the angels, therein is a sign for you if you are true believers. 

When Talut marched forth with his army, he said, "Allah will test you at a certain river, anyone who will drink from its water, shall cease to be my soldier and those who will not drink to quench their thirst with its water except a sip or so from the hollow of their hands shall fight on my side."  They all drank from it, in spite of this warning, except a few of them....

When they advanced to face Jalut (Goliath) and his warriors they prayed, "Our Rabb fill our hearts with steadfastness, make our steps firm and help us (give us victory) against the unbelievers."  They put the unbelievers to flight by the leave of Allah and Daud (David) killed Jalut."  Quran, Al-Baqarah, 2:247-251
