The importance of ikhlas(sincerity).

 The importance of ikhlas(sincerity).

Alhamdulillah, sincerity, Al Ikhlas is something very important as believers to have in any deed we do. 

We should do it for the sake of Allah. 

Allah says, 

Al-Bayyinah 98:5

And they were not commanded except to worship Allāh, [being] sincere to Him in religion, inclining to truth, and to establish prayer and to give zakāh. And that is the correct religion.

Without ikhlas, whatever good deed we do is never accepted. 

As reported in the hadith, 

Abdullah bin 'Abbas (May Allah be pleased with them) reported:

Messenger of Allah (ﷺ) said that Allah, the Glorious, said: "Verily, Allah (SWT) has ordered that the good and the bad deeds be written down. Then He explained it clearly how (to write): He who intends to do a good deed but he does not do it, then Allah records it for him as a full good deed, but if he carries out his intention, then Allah the Exalted, writes itdown for him as from ten to seven hundred folds, and even more. But if he intends to do an evil act and has not done it, then Allah writes it down with Him as a full good deed, but if he intends it and has done it, Allah writes it down as one bad deed". [Al-Bukhari and Muslim].

Riyad as-Salihin 11.

It is narrated on the authority of Amirul Mu'minin, Abu Hafs 'Umar bin al-Khattab (ra) who said:

I heard the Messenger of Allah (ﷺ) say: "Actions are (judged) by motives (niyyah), so each man will have what he intended. Thus, he whose migration (hijrah) was to Allah and His Messenger, his migration is to Allah and His Messenger; but he whose migration was for some worldly thing he might gain, or for a wife he might marry, his migration is to that for which he migrated." [Bukhari & Muslim]
