AsalamuAlaykum wa Rahmatullahi wa barakatu,
What is the authenticity of these ahadith:
Whoever calls the adhan for 12 years, Jannah will become mandatory for him [Ibn Maajah]
Whoever dies and is free from three: arrogance, grudges and debt will enter Jannah. [Tirmidhi]
Whoever repeats after the muadhdhin from his heart will enter Jannah. [Abu Dawud]
They are from the most authentic collections after the two Sahihs and none of them was flagged as a forgery so they should be considered authentic and put into practice, and Allah knows best.
