And when it was from the reward that is obtained from the causes of happiness in this world; Allah, the Most High, said - reminding them of some of that; reminding them of some of what He addressed them with; so that they may proceed to separate from the disbelievers; and stand at its limits; whatever they may be -: "O you who have believed"; meaning: those who have believed in Allah; and His Messenger; and His Book; "remember the favor of Allah"; meaning: the One who encompasses everything with power and knowledge; "upon you"; He magnified it by its ambiguity; then He increased its magnification by mentioning its timing; so He said: "when"; meaning: at the time; "a people intended"; meaning: they have strength and might; and the ability to act upon what they are in; "to extend their hands towards you"; meaning: with fighting; and killing; and it includes - along with what has been mentioned of the causes of its revelation - what happened on the morning of the night of Al-Aqabah when Quraysh plotted against the pledge; so when it was confirmed to them, they sought the people of the pledge but they missed them; except that they caught up with Sa'd ibn 'Ubadah at the end; and Al-Mundhir ibn 'Amr; the brother of Banu Sa'idah; and both of them were leaders; as for Al-Mundhir, he was able to escape them; but as for Sa'd, they captured him; they tied him up; and they began to strike him; until Allah saved him from them by Jubayr ibn Mut'im; and Al-Harith ibn Harb ibn Umayyah; due to the alliance between him and them; so it was in the context of the verse after the verse of the covenant; which was greatest on the night of Al-Aqabah; the greatest reminder of that; "so He restrained their hands from you"; meaning: with your fewness; and their multitude; and your weakness; and their strength; and there was no supporter for you except the One you believed in that night; and you relied upon Him; and you pledged allegiance to His Messenger; so He restrained some of the enemies' hands from each other; and if He had willed, He would have empowered them over you; just as He empowered the son of Adam over his brother; and it should be known that the story attributed in some tafsirs here to Banu Qurayzah in seeking assistance in the blood money of the two slain is actually for Banu Al-Nadir; and it was the reason for their expulsion.

And when He commanded them to remember the favor; He turned to that command with the command to fear the One who bestows blessings that He may change His favor into wrath; so He said: "And fear Allah"; meaning: the King whose vengeance cannot be endured; for there is no equal to Him; in caution from Him empowering your enemies against you; and from other than that of His might.

And when the decree was: 'Upon Allah alone in every situation, so place your trust; for He is worthy of the victory of whoever turns to Him; He then referred to His saying - generalizing and linking the ruling to the description -: ﴿And upon Allah﴾; meaning: alone; for there is nothing like Him; ﴿So let the believers place their trust﴾; meaning: at all times; for He prevents them if He wills like this prevention; and if the situation intensifies; and the matter becomes severe; so place your trust; and do not retreat from your enemies whom Allah has promised you their lands; and their homes; and their children; and do not fear their numbers; just as the Children of Israel feared - as will be narrated to you -; and His saying here: 'the believers'; and in the story of the Children of Israel: 'If you are believers'; is a strong bond; indicating the status of the two groups; and at that time it was good to follow it with what has preceded regarding the matter of the pass; and the matter of Banu Nadir; in their breaking of their covenant; and their treachery; with what they intended regarding the killing of the Prophet, blessings and peace be upon him; by throwing a stone upon him from the roof of the house where they seated him beside it; by His saying - indicating that the Jews have long been in breach; warning the believers not to be like them in breach; so that what befell them from humiliation does not befall them; and informing that His habit - glorified and exalted is He - in imposing obligations is ancient; not specific to them; rather it is general for His servants; and He has charged the people of the Book; honoring them with what He has charged them with; and He encouraged them; and warned them; to compete with them in obedience; for when the matter is general, it becomes easy; and when a person competes, he strives to take the prize; and He confirmed the news with that so that it is not thought due to their intense preoccupation with themselves that they had no prior covenant before that; so He said (the Most High) -:
