Allah is mercyful

يَا أَيُّهَا الَّذِينَ آمَنُوا تُوبُوا إِلَى اللَّهِ تَوْبَةً نَّصُوحًا عَسَىٰ رَبُّكُمْ أَن يُكَفِّرَ عَنكُمْ سَيِّئَاتِكُمْ وَيُدْخِلَكُمْ جَنَّاتٍ تَجْرِي مِن تَحْتِهَا الْأَنْهَارُ يَوْمَ لَا يُخْزِي اللَّهُ النَّبِيَّ وَالَّذِينَ آمَنُوا مَعَهُ ۖ نُورُهُمْ يَسْعَىٰ بَيْنَ أَيْدِيهِمْ وَبِأَيْمَانِهِمْ يَقُولُونَ رَبَّنَا أَتْمِمْ لَنَا نُورَنَا وَاغْفِرْ لَنَا ۖ إِنَّكَ عَلَىٰ كُلِّ شَيْءٍ قَدِيرٌ

O you, those who have faith! Turn to Allah with sincere repentance: In the hope that your Lord will remove your bad deeds from you and admit you to gardens beneath which rivers flow,- the Day that Allah will not permit to be humiliated the Prophet and those who believe with him. Their Light will run forward before them and by their right hands, while they say: Our Lord! Perfect our light for us, and grant us forgiveness: for Thou hast power over all things.(66/8)

May Allah blessings and favours be upon Mohammad(pbuh) his family and companions and all those who follows Him(pbuh) until the day of judgement.
And We have sent you (O Muhammad) not but as a mercy for the worlds.(Quran 21:107)
