The Prophet (PUH) said :The repentent is like sinless & is accepted as long as one isnot dying & sun didnot rise from the west .As for tongue .those believing in Allah & hereafter should say good words or shut up,honor their guests , treat neighbours well & join their relatives .Most hell access:Tongue & sex organs so those guaranteeing them will be guaranteed heaven .Most heaven access:Allah fear & good manner. A man may utter the good word that leads to Allah satisfaction so Allah guarantees his satisfaction over him till he meets him & he may utter evil word that dissatisfy Allah & fall by it in hell for 70 autumns .This guiding to the good is like good doer & will have same reward as his follower & if Allah guided by you 1 person is better for u than red camels
Acts are judged by fins & a man may continue to do evil deeds but have good fin ending him in heaven .Hadiths
Your Duaa is trapped from the till u give salutations to prophet Mohammed. the best times Allah respond to your asking are in rainfall, when armies meet, before u end your imposed prayer, when u r fasting or being oppresed,between call to prayer and prayer and at midnight as Allah goes down to the lowest sky asking if there is a repentant or a person in need so as to respond to him.
Night praying is the believer honor. Saying subhan Allah and thanks 2 Allah 100times covers your sins even if they were like sea foam as in hadiths.
