Narrated Aboo Hurayrah (may Allaah be pleased with him): Allaah’s Messenger (peace and blessings of Allaah be upon him) said:
“Allaah does not accept the prayer of any one of you if he nullifies his state of purification, until he purifies himself once again [by Wudoo or Ghusl].”
Important Points Derived from the Hadeeth:
1. The Prayer of the one who has invalidated his state of purification is not accepted until he purifies himself once again, from the state of major or minor impurity [according to one’s need].
2. Al-hadath (passing wind, urine, etc) nullifies the Wudoo’, and invalidates one’s Salaah, if the hadath occurs during the prayer.
3. The intended meaning of: “Allaah does not accept the prayer” – is that the prayer is not correct (Saheeh), nor does one even get credit (Ij-zaa’) for its performance.
4. The hadeeth indicates that at-Tahaarah (the state of purification) is a necessary pre-condition for the correctness (Sihhah) of the prayer.
