Those who love Imam Hussein (as) will reach the spiritual perfections and position by attending the mourning gatherings for Imam Hussein (as) and weeping over the tragedies that befell upon him. This is the easiest and fastest way to God's proximity.
منِ اسْتَحْسَنَ قَبيحاً كانَ شَريكاً فيهِ
Imam Jawad (as):
Whoever approves of an evil thing or a bad deed bears its sin and burden and is considered as a partner with the doer.
