The Islamic Obligation to Record Menstrual Cycles

It is obligatory for every woman to record her menses, lochia, and purity habits according to Islamic law. This requirement serves a crucial purpose when problems with abnormal bleeding occur, as the last menses, lochia, or purity habit a woman experienced is used to resolve her issue and distinguish between the types of blood.

Prophetic Foundation for Recording Habits

This methodology is based upon various statements transmitted from the Prophet ﷺ. When the female Companions who experienced abnormal bleeding asked the Prophet ﷺ about how to deal with their circumstance, the Prophet ﷺ instructed them to stop praying for the amount of days that they used to menstruate, and to take a ghusl and resume praying after those days elapsed.

Thus, the way to resolve a woman's problem will be built upon what she saw in the past. Abnormal bleeding often occurs when a woman least expects it, and her habits are needed to clarify the rulings related to any bleeding that she is seeing.

Essential Information to Record

A woman must record:

  • The date and time any vaginal blood begins, including the spotting of blood
  • The date and time any vaginal blood ends

Methods for Recording Menstrual Data

Some women use a small notebook as a diary to record their dates. Others log their dates and times using an Excel sheet. By far, the most popular option is to use a period phone app. This is certainly a convenient option.

If a woman chooses to use an electronic device or program to keep track of her habits and dates of bleeding, it is best to create a backup copy and store it in a second place as a safeguard.

Additional Considerations for Blood Colors

If possible, it is advisable for women to be aware of the colors of blood they see just in case another madhab is used to resolve their problem.

Sample Record Format

A proper record should include detailed information about bleeding patterns. For example:

  • January 5th 1 pm to January 10th 2:15pm: 5 days, 1 hour and 15 mins of blood, followed by 22 days of purity
  • February 1st 2:15 pm to February 8th 4:15pm: 7 days and 2 hours of blood, followed by 30 days, 4 hours and 45 mins of purity
  • March 10th 9 pm to March 17th 10:15pm: 7 days, 1 hour and 15 mins of blood, followed by 22 days and 45 mins of purity

This detailed tracking helps establish clear patterns that can be referenced when understanding the habit in Hanafi menstruation rulings or when dealing with irregular bleeding situations.

Conclusion

Recording menstrual cycles is not merely recommended but obligatory for Muslim women. This practice ensures that when abnormal bleeding occurs, women have the necessary information to make proper Islamic rulings about their worship and ritual purity. Whether using traditional notebooks or modern apps, maintaining accurate records with backup copies is essential for following Islamic guidance correctly.
