Warning of not being cautious about impurity
A Muslim must always maintain purity. Any kind of impurity should be avoided from touching the body or clothes, requiring vigilance. Purity comes in two forms: natural purity, like staying away from impure substances, and ritual purity, such as performing ablution (wudu) and bathing (ghusl).
The reasons why ablution and bathing are obligatory are seen in the reasons for ablution and bathing, whether or not they are necessary for prayer, which are best taken care of by ablution and bathing when necessary for prayer.
And it is best to be pure immediately if impure substances are touched on the body or clothes. It is necessary to be pure during prayer time.
Usually, a person becomes more impure due to impurities. One's own impurities, the impurities of a young child, the impurities of a wild animal. There is a high probability of getting into the body. In this case, if you do not stay alert, it will go from the body.
Man has two shoulders on either side. In addition to this, for various reasons, the angel comes to the side of man. The angels do not like impure substances. So it is best to stay in a pure state at all times.
If someone is not careful to avoid impurities from urine and their body's impurities, then the punishment of his grave is known from the hadith. There is a hadith described by Ibn Abbas (may Allah be pleased with him). He said,
Once the Messenger of Allah (peace be upon him) was going to a garden near Medina or Mecca. When he heard the sound of two such people whose graves were being punished. Then the Messenger of Allah (peace be upon him) said, "These two are being punished, although they are not being punished for any major sin." Then the Prophet (peace be upon him) said, "Yes, one of them is not taking precaution against the impurity of his urine and the other is creating defamation."
Then the Prophet (peace be upon him) brought a stalk of date-palm and broke it into two pieces and placed one piece on each grave. The companions wanted to know why they did it. If these two pieces (stalks) dry out until then (as long as they are not dried), some leniency will be given to them. (Bukhari 216, Muslim 570)
It is also important not to gain purity properly from urine. The Prophet (peace be upon him) said, "I am like your father. I will teach you everything. When you go to the bathroom, do not sit facing the Kaaba or sit behind it. Do not use the right hand or cleanliness." The Prophet (peace be upon him) used to ask to use three dirties and to be cleaned with cow dung and lime. (Abu Dawood 7)
In another hadith, Abu Bakr ibn Abi Shaiba (may Allah be pleased with him) describes, "Mu'awiyah (may Allah be pleased with him) said, 'Aisha (may Allah be pleased with her) meant women and said,' You give instructions to your husbands so that after using the bathroom they wipe the remnants of the bathroom with water. The Prophet (peace be upon him) used to do the same. I am ashamed of them. (Musanaff Ibn Abi Shaiba 1629, Tirmidhi 19, Nasai 46)
It is also sinful not to gain purity properly from urine. This is a unique feature of Christians and the reason for which the grave is punished
