Imam Saadi رحمه الله

Making Dua for a person is one of the best proofs of
His love for that person, because he does not Supplicate except for those whom He loves

[Tayseer Al-Karim Al-Rahman 732/1]

Ibn al-Jawzi رحمه الله said:

"Work for a day, the day you die, so that you'll be laughing with joy, while they'll be crying for you."

Repentance of the Middle Rank

The smaller your good deeds are in your eyes, the greater they are with Allah, and the greater they are in your heart the smaller with Allah, and the opposite is true for your bad deeds. Whoever knows Allah and His right and the worship that is owed His greatness, his good deeds vanish in his eyes and become insignificant. He realises that they are not what will save him from His punishment, for the worship that befits His Majesty is of a different nature and caliber altogether. The more he does of it, the smaller and less significant he finds it, because the more he engages in it the doors of Allah's knowledge and nearness are opened to him and his heart witnesses His greatness and magnificence against which all deeds, even if they were all the deeds of men and jinn brought together, are insignificant. If they appear abundant in his eyes, he is veiled from Allah the Almighty, deprived of the inner awareness of Him and His right. The greater this awareness and his self-awareness, the greater his sins in his eyes, for he comes to witness the Truth and His right and his own utter deficiency in performing it in the way that the Lord loves and is pleased with.
