Strive for righteousness when performing prayers.

This hadith speaks about the importance of seeking righteousness in prayer. It was narrated by Ibn Mas'ud that Allah's Prophet led them in the Zuhr prayer and he offered either more or less rak'at, and it was said to him, "O Allah's Messenger! Has the prayer been reduced, or have you forgotten?" He asked, "What is that?" They said, "You have prayed so many rak'at". So he performed with them two more prostrations and said, "These two prostrations are to be performed by the person who does not know whether he has prayed more or less (rak'at) in which case he should seek to follow what is right. And then complete the rest of the prayer and perform two extra prostrations". This hadith teaches us that if we are uncertain about how many raka’ats we have prayed during our salah then we should strive for righteousness by completing our salah with an additional two sajdahs. We must always strive for righteousness when performing our prayers as it will bring us closer to Allah SWT.
