I 
mam Ahmad bin Hambal Rahimakumullah (Imam Shafi'i's disciple) is also known as Imam Hambali. At the end of his life he told the story;
One time (when I was old) I did not know why I wanted to go to one city in Iraq. Though there is no promise the same people and no need.
Eventually Imam Ahmad went alone to the city of Bashrah. He told me stories;
When I arrived there Isya 'time, I joined the prayers in the mosque congregation, my heart felt calm, then I want to rest.
As soon as the prayers and worshipers break up, Ahmad priests want to sleep in the mosque, suddenly Marbot mosque comes to see Imam Ahmad while asking; "What are you doing here, shaykh?"
Marbot does not know if he is Imam Ahmad. And Imam Ahmad did not introduce himself.
In Iraq, everyone knows who imam Ahmad, a great scholar and hadith scholar, a million hadith memorized, very pious and zuhud. At that time there was no photo so people do not know his face, just his name is famous.
Imam Ahmad replied, "I want to rest, I am a traveler."
Marbot said, "No, no sleeping in the mosque."
Imam Ahmad recalled,
"I was pushed by the man to get out of the mosque, After leaving the mosque, locked the door of the mosque, then I want to sleep on the terrace of the mosque."
When he was lying on the terrace of his Marbot mosque came again, angry at Imam Ahmad. "Want to do more shaykh?" _ Said marbot.
"Want to sleep, I'm a traveler" _ said Imam Ahmad.
Then the marbot said;
"Inside the mosque is not allowed, on the terrace of the mosque is also not allowed." _ Imam Ahmad expelled. Imam Ahmad recalled, "I was pushed up the street."
Beside the mosque there is a bread seller (small house at the same time to make and sell bread). The bread seller is making the dough, while seeing the incident Ahmad priest was pushed by the marbot.
When Imam Ahmad reached the streets, the bread seller called from afar; "Let the shaykh, you may stay in my place, I have a place, though small."
Imam Ahmad said, "Good". Imam Ahmad entered his house, sitting behind the baker who was making bread (by still not introducing who he was, just saying as a traveler).
This bread seller has a unique attitude, if imam Ahmad invites to speak, he answered. Otherwise, he keeps making bread dough while * (continuously) * pronounces * ISTIGHFAR. * _ "Astaghfirullah" _
When giving salt, astaghfirullah, breaking eggs_astaghfirullah_, mixing wheat astaghfirullah.
He always said istighfar. A noble habit. Imam Ahmad watched.
Then Imam Ahmad asked, "how long have you been doing this?" _
The man replied;
"It's been a long time since sheikh, I've been selling bread for 30 years, so ever since."
Imam Ahmad asked;
"What is the result of this deed?"
The man replied;
"(because wasilah istighfar) there is no lust or desire that I ask, except MUST be granted God, everything I ask ya Allah ...., immediately realized."
The Prophet once said;
"Whoever keeps the istighfar, then Allah will make a way out for him from all problems and Allah will give rizki from the unexpected path."
Then the man continued, "All is granted by God except one, still one that God has not given."
Imam Ahmad was curious and then asked;
"What is that?"
Said the man;
"I ask Allah to be reunited with Imam Ahmad."
Immediately Imam Ahmad bertakbir, "Allahu Akbar ..!
- God has brought me away from Baghdad to go to Bashrah and even - until pushed by mosque marbot - Up to the street it turns out because ISTIGHFARMU. "*
The baker was aghast, praising God, it was Imam Ahmad who was in front of him.
He immediately hugged and kissed the hands of Imam Ahmad.
