Acts of Worship

What are the spiritual dimensions and rulings pertaining to the Janazah prayer? How do we pray it, and why do we recite what we do? Does it matter how many people attend the Janazah?

Du’a to recite during Janazah prayer:

‏ اللَّهُمَّ اغْفِرْ لِحَيِّنَا وَمَيِّتِنَا وَشَاهِدِنَا وَغَائِبِنَا وَصَغِيرِنَا وَكَبِيرِنَا وَذَكَرِنَا وَأُنْثَانَا اللَّهُمَّ مَنْ أَحْيَيْتَهُ مِنَّا فَأَحْيِهِ عَلَى الإِسْلاَمِ وَمَنْ تَوَفَّيْتَهُ مِنَّا فَتَوَفَّهُ عَلَى الإِيمَانِ اللَّهُمَّ لاَ تَحْرِمْنَا أَجْرَهُ وَلاَ تُضِلَّنَا بَعْدَهُ ‏‏

Oh Allah, forgive our living and our dead, those who are present and those who are absent, our young and our old, our males and our females. O Allah, whomever of us You cause to live, let him live in Islam, and whomever of us You cause to die, let him die in (a state of) faith. Oh Allah, do not deprive us of his reward, and do not let us go astray after him.
