And when Saul marched out with his army, he warned: "Allah is going to put you to a test by the side of a river: whoso drinks of its water shall cease to be my companion: he alone shall be~my companion who does not quench his thirst with its water: one may, however, take except a few, drank their fill of it. Afterwards when Saul, and those who had believed with him, crossed the river and advanced forward, the former said to Saul, "We have no power left this day to fight against Goliath and his hosts." But those who believed that one Day they shall meet Allah, declared, "lt has often been that a small host has, by Allah's grace, overcome a big host: for Allah is with those who show fortitude." 249 When they advanced to meet Goliath and his forces, they prayed: "Our Lord! Pour out constancy on us and make our steps firm: Help us against those that reject faith." 250 By Allah's will they routed them; and David slew Goliath; and Allah gave him power and wisdom and taught him whatever (else) He willed. And did not Allah Check one set of people by means of another, the earth would indeed be full of mischief: But Allah is full of bounty to all the worlds. 251 These are the messages of God. We recite them to you in all truth, as indeed you are one of the apostles. 252 ۞ These apostles: We have preferred some of them above some others: of them are some unto whom Allah spake, and some He raised many degrees. And We vouchsafed unto Isa, son of Maryam, the evidences, and We aided him with the holy spirit; and had Allah so willed those who came after them had not fought among themselves after the evidences had come unto them but they differed; then of them some believed and of them some disbelieved. And had Allah so willed, they had not fought among themselves, but Allah doth whatsoever He intendeth. 253
