Best times to make Dua (Supplication)

From sister Shaykha:

Asalaamu Alaaikum brothers and sisters,

There is a sister here by the name of tasnimoo, please make dua for this sister that she gets better. What happened was she got tricked by some evildoers (pretending to be her friends) and she was drugged by them, she was even pronounced dead when she was in hospital. Now by the Mercy of Allah SWT she is alive, her heart beating again, but she is still in critical condition, and is need of everyone's duas here. Remember we are all one family,if one of us hurts the rest of us do too. So just imagine if this were your real blood sister in this state, please make dua that Allah SWT gives her shifa, and allows her to make it through this great trial!

Wa'alaykum Asalaam!

MAy ALLAH(SWT)cure our sister fast & all the sick muslimeen.ALLAHUMA AMEEEEEEEEN!!!!
