As Muslims we should always fear Allah because if Allah was to punish u and all of mankind (the Muslims and the kafirs) for your sins he would not have been unjust to anyone, though there are scholars and righteous worships among us.
Abu Dawud records on the authority of Zayd ibn Thabit (radiAllaahu ‘anhu) that the Messenger of Allah (salAllaahu alayhi wa sallam) said, “Were Allah to punish the inhabitants of the heavens and the inhabitants of the earth, He could do so without having oppressed them in any way. Were He to show them mercy, His mercy would be better for them than their deeds.” Abu Dawud #4699 and ibn Majah #77. It was declared sahih by ibn Hibban [#727] and Albani, Sahih al-Jami’ #5244
Even if Allah punished the prophet Isa (Jesus) and the prophet Mohammed for their sins, he would not be unjust though they are the best of mankind to have walked this earth.
Ibn Hibban #659 records on the authority of Abu Hurayrah that the Messenger of Allah (salAllaahu alayhi wa sallam) said, “Were Allah to take me and Isa to account for our sins, he could punish us without wronging us in the least!” It was declared sahih by ibn Hibban and Albani, Sahih al-Taghrib #2475
If Allah was to punish us justly he would destroy us all.
Allah, Exalted is He, says: “If Allah took mankind to task by that which they deserve, He would not leave a living creature on the surface of the earth; but He grants them reprieve unto an appointed term, and when their term comes – then verily Allah is Ever All-Seer of His slaves.” [Fatir (35):45]
So think how merciful Allah is to us (Muslims) that he does not destroy us for our sins in this world and in the hereafter he will allow the Muslims in to jannah though we do not deserve it.
Hence the Messenger of Allah (salAllaahu alayhi wa sallam) said, “…Were He (Allah) to show them mercy, His mercy would be better for them than their deeds.” Abu Dawud #4699 and ibn Majah #77. It was declared sahih by ibn Hibban [#727] and Albani, Sahih al-Jami’ #5244
Also Abu Dawud mentions in the Sunnan, related by Ahmad : It is in the Saheehah (when you hear as-Saheehah it means it is authenticated by Shaikh Naasir ud-Din al-Albaani in his authentic books of narrations – Hadith No. 959) :The Prophet (sallallaahu ‘alayhi wa sallam) said : “This my Ummah, is a Ummah that has mercy upon it, ‘Marhooma’- a Ummah that has mercy that’s been wrapped in Mercies;…” And the wording of Abu Dawud is : ‘This Ummah reminds of the Ummah, that Allaah has placed His mercy upon…”
Plus the prophet said, “Allah made mercy one-hundred parts. He held back ninety-nine parts, and sent down one part to earth. It is from that part that creatures show mercy to each other, such that a mare will lift her hoof over her foal, fearing that she might harm him.” Sahih al-Bukhari no. 6066, Kitab al-Adab
Furthermore the messenger said, “Allah says, Great and Glorious is He, ‘My mercy outstrips my wrath.’” Sahih Muslim no. 7146, Kitab al-Tawbah
However though Allah is mercy full to attain Allahs mercy a Muslim must be merciful to others, the messenger of Allah said, “Allah is not merciful to one who is not merciful to people.” Sahih al-Bukhari no. 7465, Kitab al-Tawhid
Ya Allah grant all the Muslims living your mercy in this world and in the hereafter and grant the dead Muslims and the living mercy in the hereafter, we beg u for your mercy as we are in need of it always and you are Ar-Rahman and Ar-Raheem.Ameen.
