What is Iddah?
The Period for Widow:
The waiting period for widow is four months and ten days. So, this period is in Quran as,
Waiting period for a pregnant woman is till the birth of the child.
“And for those who are pregnant. their Iddah (prescribed period) is until they lay down their burden.” (Surah At-Talaq, Verse 4)
What is mourning?
The Prophet (SAW) is reported as saying,
“It is not lawful for a woman who believes in Allah and the Last Day that she should mourn a dead person for more than three days except in the case of her husband whom she should mourn for four months and ten days.” (Muttafiq ‘Alaih)
Mourning is to refrain from adornment:
In waiting period a widow is not allowed to beautify herself in anyway.
To avoid going out:
A widow should not leave the house in waiting period except it is something really important.
