“All Greatness is Attained through the Service of Hussain”

The same written in Arabic Calligraphy:

كل الخير في باب الحسين

“When will we witness your return, Ya Mahdi”

including calligraphy with a line of Arabic poetry reading
“مات التصبر في انتظارك يا محيي الشريعة”
meaning “Patience has died waiting for you, O’ protector of Shariah”
