Surah At-Taubah, Ayat 115-116

Ayat 115. And Allah will never lead a people astray after He has guided them until He makes clear to them as to what they should avoid (via Quran and Sunnah). Verily, Allah is the All-Knower of everything.

Ayat 116. Verily, Allah! Unto Him belongs the dominion of the heavens and the earth, He gives life and He causes death. And besides Allah you have neither any protector (or guardian) nor any helper. 

Hazrat Zaid bin Arqam (May Allah be pleased with him) reported; "One day Messenger of Allah  [SAWW](PBUH) stood up to deliver a Khutbah at a watering place known as Khumm between Makkah and Al-Madinah. He praised Allah, extolled Him, and exhorted (us) and said, O people, I am a human being. I am about to receive a messenger (the angel of death) from my Rubb and I will respond to Allah's Call, but I am leaving with you two weighty things: the first is the Book of Allah, in which there is right guidance and light, so hold fast to the Book of Allah and adhere to it.' He exhorted (us to hold fast) to the Book of Allah, and then said, `The second is the members of my household, I remind you (to be kind) to the members of my family. I remind you (to be kind) to the members of my family. [Muslim Hadith # 5920]. 

Another narration Messenger of Allah  [SAWW](PBUH) said, "I am leaving behind me two weighty things. One of them is the Book of Allah; that is the strong rope of Allah. Whosoever holds firmly to it, will be the guided, and whosoever leaves it goes astray". [Muslim Hadith # 5922]. 

Lesson : as mentioned above in Surah At-Taubah Ayat 115. "Allah will never lead a people astray after He has guided them until He makes clear to them as to what they should avoid." This Hadith brings out the following points: 1. Messenger of Allah  [SAWW](PBUH) was a human being. He too was subject to the inevitable law of death. 2. It stresses upon the establishment of a firm bond with the Book of Allah (the Qur'an) and lays emphasis on showing respect. 3. The members of the Prophet's family are classified into two categories: Firstly, wives of Messenger of Allah [SAWW](PBUH) or Mothers of the believers. This is established from the categorical Verses of the Noble Qur'an. Secondly, persons who have close relationship with Messenger of Allah [SAWW](PBUH) . They are Banu Hashim and Banu Abdul-Muttalib.
