After you attend a Janaza of a dead Muslim, you see his/her dead body and bury him/her, does your Wudu stands or broken. Some Imaams say that you should have a bath/shower and then perform Wudu to say your prayers. Can you please clarify what our Shariah says?

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.

Ablution is not invalidated by attending the funeral prayer, or by looking at the dead body, or by attending his burial. If one says that ablution is invalidated by one of the above, then he is telling a lie on the religion of Allaah. However, it is desirable for a person who washed the dead body to perform Ghusl (ritual bath), and whoever carried the coffin to perform ablution as the Prophet said: "Whoever washes a dead person he should perform Ghusl and whoever carries a dead body, he should perform ablution." [Abu Daawood]. So, it is desirable to do the above [but it is not an obligation]; the evidence is that Ibn 'Umar said: "We used to wash the dead, so some of us performed Ghusl, and others did not." [Al-Bayhaqi and Ad-Daaraqutni]

Allaah Knows best.
