Al-Baqarah 2:249 فلما فصل طالوت بالجنود قال ان الله مبتليكم بنهر فمن شرب منه فليس مني ومن لم يطعمه فانه مني الا من اغترف غرفة بيده فشربوا منه الا قليلا منهم فلما جاوزه هو والذين امنوا معه قالوا لا طاقة لنا اليوم بجالوت وجنوده قال الذين يظنون انهم ملاقو الله كم من فية قليلة غلبت فية كثيرة باذن الله والله مع الصابرين ٢٤٩

When Talut set out with his forces, he said to them, ‘God will test you with a river. Anyone who drinks from it will not belong with me, but anyone who refrains from tasting it will belong with me; if he scoops up just one handful [he will be excused].’ But they all drank [deep] from it, except for a few. When he crossed it with those who had kept faith, they said, ‘We have no strength today against Goliath and his warriors.’ But those who knew that they were going to meet their Lord said, ‘How often a small force has defeated a large army with God’s permission! God is with those who are steadfast.’
