Perform your ablutions properly before engaging in any religious activities such as prayer or reciting Quran .

This hadith is about the importance of performing ablution before prayer or any other religious activity. It was narrated by four companions of Prophet Muhammad (PBUH): Khalid bin Walid, Yazid bin Abu Sufyan, Shurahbil bin Hasanah and 'Amr bin 'As that they heard the Messenger of Allah say “Complete the ablution. Woe to the heels because of Hell-fire”. This hadith serves as a warning for Muslims to perform their ablutions properly before engaging in any religious activities such as prayer or reciting Quran; otherwise they will be punished in hellfire for not doing so. It also teaches us that we should take our religion seriously and follow its teachings with utmost care and attention so that we can avoid being punished in this world or hereafter.
