Fasbir lihukmi rabbika wala takun kasahibi alhooti ith nada wahuwa makthoom (surah Qalam: 48)

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

(68:48) So bear with patience until the Judgement of your Lord *31 comes, and do not belike the man in the fish (i.e., Jonah) *32 who called out, choking with grief: *33

Fasbir lihkmi rabbika wa laa takun kasaahibil boot; iz naadaa wa huwa makzoom

*31) That is, "The time when Allah will issue His decree about your success and victory and your opponents' defeat, is yet far off. Till then you should go on enduring with patience whatever hardships and afflictions you may have to face in the way of preaching the Faith. "
*32) That is, "Do not behave impatiently as did the Prophet Jonah (peace be on him), who an account of his impatience was driven into the fish's belly." Immediately after exhorting the Holy Prophet (upon whom be peace) to have patience until Allah issued forth His decree, to tell him not to behave like the Prophet Jonah by itself gives the meaning that the latter had shown some kind of impatience before Allah gave His decision and thus had incurred His wrath. (For explanation, see Yunus; 98, and E.N, 99 on it; Al-Anbiya': 87-88 and E.N.'s 82 to 85; As-Saaffat: 139-148 and E.N.'s 78 to 85).
*33) In Surah Al-Anbiya' it has been explained thus: "From inside the fish's belly and the darkness of the sea, the Prophet Jonah invoked Allah, saying: La ilaha ills ants subhanaka inni kuntu min-az-zalimin: `There is no god but You; glory be to You: I had indeed committed a wrong.' Thereupon Allah heard his prayer and delivered him from this affliction." (vv. 87-88).
