The verb yaghill, read with an open vowel (fatḥa), is the predominant pronunciation.⦗1⦘ It is also said, “His breast became ghill,”⦗2⦘ meaning that he is deceitful, spiteful, and filled with malice. Thus the heart of a Muslim does not harbor rancor toward these three qualities—the very three mentioned earlier in His words: “Allah is pleased for you with three things: that you worship Him without associating anything with Him; that you all hold fast to the rope of Allah and do not divide; and that you give sincere counsel to those whom Allah has placed over your affairs.” When Allah is pleased with these matters for us, the believer’s heart—which loves whatever Allah loves—cannot loathe or detest them such that it retains any ill-feeling toward them. On the contrary, the believer’s heart cherishes them and is content with them.⦗3⦘
(1) Abu Ubayd al-Qasim ibn Sallam comments: “Concerning the Prophet’s words, ‘thalathun la yaghillu ʿalayhinna qalbu muʾmin…’ (‘three things over which a believer’s heart does not harbour rancour …’), the narration is transmitted with two vocalisations: la yaghillu and la yughillu. Whoever reads yaghillu, with the vowel fatḥa, derives it from ghill, meaning malice, spite, and enmity; whoever reads yughillu, with ḍamma, relates it to ghulul, i.e. betrayal or embezzlement.” Gharib al-Hadith, 1/199-200.
(2) Thus in the base manuscript; the correct form is ghalla ṣadr-hu yaghillu (“his chest became filled with rancour”).
(3) This sense, cited by Shaykh al-Islam, is corroborated by al-Darimi’s version of the hadith: “la yaʿtaqidu qalbu Muslim ʿala thalathi khisal illa dakhala al-janna …” (“No Muslim’s heart embraces three qualities without his entering Paradise …”). Sunan al-Darimi, 1/75.
