[Once] a servant of God [people] who lived in Yazd, had a hard problem. Meanwhile, he had the honor of visiting His Excellency SÄhib al ZamÄn (mGehr), but he couldn’t recognize the ImÄm!! Anyhow, the Excellency stated:
Recite SÅ«rah YÄsÄ«n. Then, as you see the word “Mubin مبین†which is repeated 6 times in [the Surah], ask God for your needs. Do the same at the end of the Surah. May God answer your prayers [and fulfil them].
He kept on, ‘When I took a look at Surah YÄsÄ«n, I saw it has 7 مبین! But when I paid attention, I realized the word مبین was repeated 6 times without ال٠and لام. And just one time it includes ال٠and لام.
Then he continued, ‘I recited the Surah, in the way the Excellency had ordered. Yes, God fulfilled my wish!’
