If Milo 3in1 has a few ingredients in packet, a faithful man (referring to both men and women) has many ingredients in themselves. Responsible, honest, helpful, healthy, clean, softness, loudness, toughness, strength, reasonable income, self-control, hard-working, provider, trustworthy, spontaneous, open minded, willing to listen, forgiving, kind and gentle and the list never stops. A human may definitely not have all these good traits however a faithful man towards Allah swt will try to achieve it. The key word here is TRY. Being faithful and trying to be faithful to Allah swt will lead us to have good characteristics in ourselves.
Wallahualam.
