Verse 249: قَالَ إِنَّ اللَّـهَ مُبْتَلِيكُم بِنَهَرٍ (He said: Allah is going to test you by a
river).
The wisdom behind this test, as perceived by this humble commentator, appears to be as follows. Not difficult to imagine is the excitement created on such occasions but there are not many who would stay firm in their hour of trial. And should such a time come, the weakness shown by such people becomes contagious making others panic as well. Allah Almighty willed that such people be pruned out. This purpose was accomplished by this test, which is very appropriate, because steadfastness is necessary in fighting. So, being patient, when water is made available without asking in a state of intense thirst, is a proof of steadfastness, and dashing for water is a proof of its absence. Later on comes the unusual: Those who drank too much water became mysteriously more incapacitated. This has appeared in Ruh al-Ma'ani on the authority of Ibn Abi Haim from Ibn ` Abbas ؓ . Now the events and sayings mentioned in this story tell us that there were three kinds of people among them:
(1) The weak in faith who failed to make the grade in their hour of
trial.
(2) The perfect who fully succeeded in their trial but did feel concerned about how low they were in numbers.
(3) The most perfect who did not bother even about that.
Allah states that Talut, the king of the Children of Israel, marched forth with his soldiers and the Israelites who obeyed him. His army was of eighty thousand then, according to As-Suddi, but Allah knows best. Talut said:
(Verily, Allah will try you) meaning, He will test you with a river, which flowed between Jordan and Palestine, i.e. , the Shari`ah river, according to Ibn `Abbas and others. He continued,
(So whoever drinks thereof, he is not of me;) meaning, shall not accompany me today,
(and whoever tastes it not, he is of me, except him who takes (thereof) in the hollow of his hand.) meaning, there is no harm in this case. Allah then said:
(Yet, they drank thereof, all, except a few of them.)
Ibn Jurayj stated that Ibn `Abbas commented, "Whoever took some of it (the river's water) in the hollow of his hand, quenched his thirst; as for those who drank freely from it, their thirst was not quenched."
Ibn Jarir reported that Al-Bara' bin `Azib said, "We used to say that the Companions of Muhammad who accompanied him on the battle of Badr were more than three hundred and ten, just as many as the soldiers who crossed the river with Talut. Only those who believed crossed the river with him." Al-Bukhari also reported this.
This is why Allah said:
(So when he had crossed it (the river), he and those who believed with him, they said: "We have no power this day against Jalut (Goliath) and his hosts.")
This Ayah indicates that the Israelites (who remained with Saul) thought that they were few in the face of their enemy who were many then. So, their knowledgeable scholars strengthened their resolve by stating that Allah's promise is true and that triumph comes from Allah Alone, not from the large numbers or the adequacy of the supplies. They said to them:
("How often has a small group overcome a mighty host by Allah's leave" And Allah is with As-Sabirin (the patient).)
