Our acts of worship must be based on the Qur'ān & Sunnah

As Muslims, all our acts of worship must be based on the Qur'ān & Sunnah; so whatever is proven in the Qur'ān & Sunnah, we do as much as we can, and whatever is not, we refrain from it. Therefore, we do not say anything after yawning, burping or passing wind; because nothing specific has been established in the Qur'ān & Sunnah in this regard.

▪What you should say when you trip/ fall: Abul Malīḥ reported on the authority of a man: “I was riding on a mount behind the prophet ﷺ. It stumbled so I said: May the devil perish! He said: do not say; may the devil perish! For when you say that, he will swell so much so that he will be like a house, and says: by my power. But say: “Bismillaah” -- In the Name of Allāh; for when you say that, he will diminish so much so that he will be like a fly.

 [Sunan Abu Dawud (4982), graded 'Sahih' by Sh. Albani] 

Dying while Adhering to the Sunnah.

From Mu’tamar bin Sulayman رحمه الله who said:

‘I visited my father while I was heartbroken and he said: ‘What is wrong?’

I said: ‘My friend has died.’

He asked: ‘Did he die upon the Sunnah?’

I answered: ‘Yes.’

He said: ‘Then do not worry about him.’

[Al-Laalkaa'iee 1/67/61]

Imam Malik ibn Anas رحمه الله (d. 179 A.H.)  said:

‘If a person meets Allaah with the equivalent of the earth in sins, but meets[1] Allaah while upon the Sunnah, then he will be in Paradise with the Prophets, the truthful, the martyrs, the righteous and how excellent are these companions.’

[Dhum al-Kalam wa Ahlihi 5/76-77]

Imam Ahmad رحمه الله (d. 241 A.H.) said:

‘Whoever died upon Islaam and the Sunnah then he has died upon all goodness.’

[Seer Alaam an-Nubala (11/296)]

Yahya bin Jafar رحمه الله said:

‘If I had the capability to increase the age of Muhammad bin Ismaeel -i.e. al-Bukhari- taken from my age I would have done so, since indeed my death is the death of one man, but his death was the going away of knowledge.’

[Tareekh al-Baghdad 2/24]

Hasan Basri رحمه الله who said:

‘O Ahl-ul- Sunnah be gentle may, Allaah have mercy on you since indeed you are from the fewest in number.’

[Al-Laalkaa'iee 1/57/19]

Thank Allaah For Favouring You With The Sunnah

Ibnul Qayyim (رحمه الله) stated: 

‘I entered upon one of our companions and there was a matter that happened with him which caused him to cry. So, I asked him about it and he said: “I remembered that which Allaah has bestowed upon me of favour from the Sunnah, knowing it, being free from the doubts of the people and their false principles, being given success to have clear intellect and sound natural disposition towards that which the Messenger came with. 

Where does Salvation lie?

The People of Knowledge who came before us used to say:

“Salvation lies in clinging to the Sunnah…”
