This dervesh knows not a style in speech,
Save this main point no exir he would teach.
From that barren land no harvest you can,
Till it is watered with blood of Hussain.1

1.         Exit; viz, elixir.
            I have used Dervesh in place of Qalandar which Iqbal has used in this quatrain. Qalandar is a Muslim sect of Faqirs (Dervish) who shave off beard and abandon wordly possessions, friends and relatives and travel from place to place worship one God (Now almost extinct).
Shabbir as in text is the title of Imam Hussain ĎAlaih-ií;Salam. (It means chief of Martyrs and Service Prayers).
