Hazrat Sheikh Moulana Zakariyya (rahmatullahi ‘alaihi) mentioned:
Once a person wrote a letter to me asking, “What is the sign that pride no longer remains with a person?” I replied that if any person finds fault with you, then you are not overcome by anger. Instead you begin to examine within your heart whether what the person has said is true or not. If after pondering and reflecting over the situation, your heart tells you that the statement the person made was correct and you suffer from that weakness, then you are immediately prepared to accept your mistake and correct yourself. If this is your condition, then this is a sign that pride has left you. However, on the converse, if after hearing the statement of that person, you are overcome by rage and anger without even taking a moment to think whether what was said was correct or not, then this is a clear sign of you having pride”. (Malfoozaate Hazrat Shaikh 1/71)
