Hadith 1038
Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) says: I heard the Noble Prophet (peace and blessings be upon him) say: "Even a little bit of showing off is shirk. Allah, the Mighty and Majestic, loves the pious, hidden, and pure people—those who, when absent, are not sought after, and when present, are not recognized. Their hearts are lamps of guidance; they will emerge from every dark, black trial."
