call them to all that is good and righteous, in order that they might turn away from the darkness of ignorance and misguidance they indulged in, to the light of guidance and the enlightenment of faith,
{and remind them of the annals (or days) of Allah}

remind them (O Musa) of Allah's days, meaning, favors and bounties which He bestowed on them when He delivered them from the grip of Fir'awn and his injustice, tyranny and brutality. This is when Allah delivered them from their enemy, made a passage for them through the sea, shaded them with clouds, sent down manna and quails for them, and other favors and bounties. Mujahid, Qatadah and several others said this. Allah said next,
{Truly, therein are Ayat for every patient, thankful (person).}

Allah says, 'Our delivering of Our loyal supporters among the Children of Israel from the grasp of Fir'awn and saving them from the disgraceful torment, provides a lesson to draw from for those who are patient in the face of affliction, and thankful in times of prosperity. Qatadah said, "Excellent is the servant who if he is tested, he observes patience, and if he is granted prosperity, he is thankful for it." It is recorded in the Sahih that the Messenger of Allah said,
"Verily, all of the matter of the believer is amazing, for every decision that Allah decrees for him is good for him. If an affliction strikes him, he is patient and this is good for him; if a bounty is give to him, he is thankful and this is good for him."
