And when Allah is mentioned alone, the hearts of those who do (39:45)

Almuntakhab Fi Tafsir Alquran Alkarim

And when the Name of Allah alone is mentioned those who deny the Hereafter grow peevish and their hearts come to be filled with aversion or disgust reflected on their countenances, whereas when other objects of worship -their false gods- are referred to, they rejoice beyond a common Joy

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(39:45) When Allah alone is mentioned, the hearts of those who do not believe in the Hereafter contract with bitterness, but when deities apart from Allah are mentioned, they are filled with joy. *64

And when Allah is mentioned alone, the hearts of those who do meaning

*64) This evil is common to almost all polytheistic people of the world, and even some unfortunate Muslims also suffer from it, They profess with the tongue that they believe in Allah, but when One Allah alone is mentioned before them, their faces arc distorted, and they say, "This man certainly does not believe in the saints and holy men; that is why he talks of Allah and Allah alone. " And if others besides Allah arc mentioned, they are delighted, and their faces brighten up with joy. Their this attitude shows as to who is the actual object of their love and esteem. 'Allama Alusi, in his commentary Ruh al-Ma ani, has related his own experience here. He says: "One day I saw that a man was invoking the help of a dead saint in his affliction. I said; O bondsman of Allah, invoke Allah, for He Himself says: 'If My servants ask you, O Prophet, concerning Me, tell them I am quite near to them. I hear and answer the prayer of the supplicant when he calls to Me," (AI-Baqarah: 186), Hearing this the man became angry, the people told me afterwards that he said: This man is a denier of the saints; and some others heard him also say: The saints answer the prayers more promptly than does Allah."

جب اکیلے اللہ کا ذکر کیا جاتا ہے تو آخرت پر ایمان نہ رکھنے والوں کے دل کڑھنے لگتے ہیں، اور جب اُس کے سوا دوسروں کا ذکر ہوتا ہے تو یکایک وہ خوشی سے کھل اٹھتے ہیں
