The issue of people’s hearts is an important and sensitive issue. The heart is called Qalb in Arabic because it changes so quickly and frequently (Taqallub – alteration, variation, ups and downs). The Prophet (peace and blessings of Allaah be upon him) said: “The heart (Qalb) takes its name from its constant changes (Taqallub). The likeness of the heart is that of a feather at the root of a tree, being turned over and over by the wind.” (Reported by Ahmad, 4/408; Saheeh al-Jaami’, 2364).
According to another report: “The likeness of the heart is that of a feather in an empty plot of land, being blown over and over by the wind.” (Reported by Ibn Abi ‘Aasim in Kitaab al-Sunnah. No. 227. Its isnaad is saheeh, see Zilaal al-Jannah fi Takhreej al-Sunnah by al-Albaani, 1/102).
Man’s heart changes constantly, as the Prophet (peace and blessings of Allaah be upon him) described: “The heart of the son of Adam changes more quickly than a pan of rapidly boiling water.” (Ibid., no. 226. Its isnaad is saheeh: Zilaal al-Jannah, 1/102), According to another report: “It changes more than a pot of rapidly boiling water.” (Reported by Ahmad, 6/4; Saheeh al-Jaami’, no. 5147).
Allaah is the One Who turns hearts around and controls them. ‘Abd-Allaah ibn ‘Amr ibn al-‘Aas reported that he heard the Messenger of Allaah (peace and blessings of Allaah be upon him) say: “The hearts of the children of Adam are as one between the fingers of the Most Merciful, and He turns them in whatever way He wills.” Then he said: “O Allaah, Controller of the hearts, direct our hearts to obey You.” (Reported by Muslim, no. 2654).
So the believer must check his heart, find out the nature and cause of the problem, and start treating it straight away, before it overwhelms him and destroys him. The matter is of the utmost seriousness, for Allaah has warned us against the heart that is hardened, closed, sick, blind and sealed.
I ask Allaah to benefit me and my Muslim brothers and sisters, for He is the One Whom we ask to soften our hearts and guide us. He is our Protector, He is sufficient for us and He is the Best Disposer of affairs.
