السَّلامُ عَلَيْكُمْ وَرَحْمَةُ اللَّهِ وَ بَرَكَاتُهْ
the ending of suratul baqarah is so powerful; the three simple phrases put together in a perfect sequence.
We ask Allah to erase our sins. Allah commands the angel on our left to desist from writing down our bad deed immediately, giving us an opportunity to repent to Him. But...if this particular time period (mentioned in the hadith) is up,
We ask Allah to shield us from our sins. This can be done with the help of our good deeds. But..if we don't have enough good deeds,
We ask Allah to have mercy on us. We must never lose hope in the merciful nature of our creator, Arhamur-raheemin.
It does not mean they were not permitted to make a mistake but that they will not be left in that wrong. For us nothing guarantees that we will be corrected or easy repentence afterwards. If there were no sins, Al-Rahman Al-Raheem would have no meaning.(this one my murabbi told me once ;))
if you remember about the hadeeth when Aishah RA asked the Prophet SAW to pray for her and so he prayed for her. Aishah RA was very happy that the Prophet SAW prayed for her and the Prophet SAW told her that he prayed that her sins would be forgiven whether they were committed in the past, the sins to be committed in the future, the sins she committed knowingly, sins she committed unknowingly, sins she committed in public and the sins she committed in private. The Prophet SAW further stated that Wallahi this is the du'aa I make not only for you but for all of the ummah and the generations that are yet to come.
I know my wording isn't that great, but this was one of the most beautiful gems from my conversation between me and my other half (during his birthday) within this week...:)
