Is a person sinful for desiring to meet his Lord and his ancestors and to see the Messenger (peace be upon him)? And are his imaginings that he is among the people of Paradise considered arrogance?

A Muslim's yearning for his Lord and for seeing his Prophet (peace be upon him) is evidence of his trust in his Lord and his belief in His promise. This yearning is only valid if accompanied by following the deeds beloved by Allah and His Messenger. A Muslim should frequently read about Paradise and what Allah has prepared for its inhabitants, so that this serves as an incentive for him to strive for it. What is mentioned in the Qur'an and Sunnah about Paradise will be found by its inhabitants. Allah Almighty says: "And therein is whatever the souls desire and [wherein] the eyes find pleasure, and you will abide therein eternally" (Az-Zukhruf: 71). The Prophet (peace be upon him) said: "I have prepared for My righteous servants what no eye has seen, no ear has heard, and no human heart has conceived." A Muslim must exert his utmost effort in obeying Allah and avoiding His prohibitions, and he must beware of relying on mere wishes without righteous deeds. For acceptable hope is to act in obedience to Allah based on light from Allah, or to repent from sins. As for hope accompanied by continued negligence and sins, it is delusion and false yearning.
