Be informed that Allah...
Be informed that Allah, the most Praised One, has described the patient ones, mentioning those who persevere in the Qur'an in more than seventy places, attaching many good things and degrees to patience and to making them its fruit: The greatest One has said: "And We appointed leaders from among them, giving guidance under Our command so long as they persevered with patience and continued to believe in Our Signs" (Qur'an, 32:24).
He has also said:" The fair promise of your Lord was fulfilled for the Children of Israel because they had patience and constancy" (Qur'an, 7:137). The Almighty has also said:" And We will certainly bestow rewards on those who patiently persevere according to the best of their deeds" (Qur'an, 16:96). He has also said: "Twice will they be given their reward because they have persevered" (Qur'an, 28:54).
He has also said: "Those who patiently persevere will indeed receive their reward without measure!” (Qur'an, 39:10). Every sacrifice has its own reward according to a measure and a calculation except perseverance. Since fasting is derived from perseverance, and since it is equivalent to half of perseverance[^3], rewards for it are handled only by Allah, the most Praised One, the most Exalted, as books of traditions tell us.
Allah Almighty has said [in a Qudsi hadith ]: "Fasting is for My sake, and I am the One Who rewards for it."[^4] Thus, He added it to Himself from among all other acts of worship, promising those who persevere that He is with them, saying: "… And persevere, for Allah is with those who persevere" (Qur'an, 8:46), hinging His support on perseverance and saying, "Yes, if you remain firm and act rightly, even if the enemy should rush headlong on you here, your Lord will help you with five thousand angels, making a tremendous onslaught" (Qur'an, 3:125).
He has gathered rewards for those who persevere which He has not for others saying: " They are the ones on whom God's blessings and mercy (descend), and they are the ones who receive guidance" (Qur'an, 2:156). Guidance, blessings and mercy are all gathered for those who persevere, and recounting all verses referring to perseverance will take quite a lengthy endeavor.
