How often do people keep knocking on someone’s door without respecting the inhabitants’ right to not respond?
How many people don’t just call someone once, twice, or three times on the phone, but rather keep calling as many as twenty times, or even more? (“I can keep ringing if there’s no answer— it’s my husband!”)
Yes, this hadith applies for family as well, so next time you feel like continuously knocking or calling someone, remember this sunnah and keep the three-times-only rule.
