(narration about the chain of narrators)

Narrated Az-Zuhri: as follows in Hadith 297. Narrated Abu Huraira: We were in the company of Allah's Apostle in a Ghazwa, and he remarked about a man who claimed to be a Muslim, saying, "This (man) is from the people of the (Hell) Fire." When the battle started, the man fought violently till he got wounded. Somebody said, "O Allah's Apostle! The man whom you described as being from the people of the (Hell) Fire fought violently today and died." The Prophet said, "He will go to the (Hell) Fire." Some people were on the point of doubting (the truth of what the Prophet had said) while they were in this state, suddenly someone said that he was still alive but severely wounded. When night fell, he lost patience and committed suicide. The Prophet was informed of that, and he said, "Allah is Greater! I testify that I am Allah's Slave and His Apostle." Then he ordered Bilal to announce amongst the people: 'None will enter Paradise but a Muslim, and Allah may support this religion (i.e. Islam) even with a disobedient man.'

Narrated Abu Musa: We were in the company of the Prophet on a journey, and whenever we ascended a high place, we used to say Takbir (in a loud voice). The Prophet said, "O people! Be kind to yourselves, for you are not calling upon a deaf or an absent one, but You are calling an All-Hearer, and an All-Seer." Then he came to me as I was reciting silently, "La haul a wala quwwata illa bil-lah." He said, "O `Abdullah bin Qais! Say: La haul a walaquwata illa bil-lah, for it is one of the treasures of Paradise." Or he said, "Shall I tell you a word which is one of the treasures of Paradise? It is: La haul a wala quwwata illa bil-lah."

Narrated Abu Musa Al-Ash`ari: The Prophet started ascending a high place or hill. A man (amongst his companions) ascended it and shouted in a loud voice, "La ilaha illal-lahu wallahu Akbar." (At that time) Allah's Apostle was riding his mule. Allah's Apostle said, "You are not calling upon a deaf or an absent one." and added, "O Abu Musa (or, O `Abdullah)! Shall I tell you a sentence from the treasure of Paradise?" I said, "Yes." He said, "La haul a wala quwwata illa billah,"

Narrated Abu Musa: We were with the Prophet on a journey, and whenever we ascended a high place, we used to say, "Allahu Akbar." The Prophet said, "Don't trouble yourselves too much! You are not calling a deaf or an absent person, but you are calling One Who Hears, Sees, and is very near." Then he came to me while I was saying in my heart, "La hawla wala quwwatta illa billah (There is neither might nor power but with Allah)." He said, to me, "O `Abdullah bin Qais! Say, 'La hawla wala quwwata illa billah (There is neither might nor power but with Allah), for it is one of the treasures of Paradise." Or said, "Shall I tell you of it?"
