The Duty of the Shi'as and Sunnis on the 21st of Ramadan
On twenty first of Ramadan, this country should mourn unitedly
if someone is Sunni, he believes in Quran
This is the text of the Quran
All the Shiite and Sunni Scholar agree
فَمَنْ حَآجَّكَ فِيهِ مِن بَعْدِ مَا جَاءكَ مِنَ الْعِلْمِ
فَقُلْ تَعَالَوْاْ نَدْعُ أَبْنَاءنَا وَأَبْنَاءكُمْ وَنِسَاءنَا وَنِسَاءكُمْ وَأَنفُسَنَا وأَنفُسَكُمْ
Based on agreement of all the Sunni and Shia scholars
Based on consensus of all the Muslims
The 'self' which the prophet of Allah brought with him on the day of Mubahela is Ali ibne Abi Talib
This is why the twenty first of Ramadan is martyrdom day of the Holy Prophet
This is the duty of every Muslim
He should do what he can on the mourning day of the Holy Prophet
