{الحَمْدُ لِلَّهِ رَبِّ العَالَمِينَ}All praise is for Allah, Lord of the worlds. [Al-Fatihah 1:2]
Allah is the Lord of all worlds: their Creator, Owner, and Controller.
{يَا أَيُّهَا النَّاسُ اعْبُدُوا رَبَّكُمُ الَّذِي خَلَقَكُمْ وَالَّذِينَ مِنْ قَبْلِكُمْ... فَلَا تَجْعَلُوا لِلَّهِ أَنْدَادًا وَأَنْتُمْ تَعْلَمُونَ}O mankind, worship your Lord who created you and those before you... so do not set up rivals to Allah while you know. [Al-Baqarah 2:21-22]
This verse combines the command to worship Allah alone with the evidence for that command: He is the One who created, provided, blessed, and controlled.
{قُلْ مَنْ يَرْزُقُكُمْ مِنَ السَّمَاءِ وَالأَرْضِ... وَمَنْ يُدَبِّرُ الأَمْرَ، فَسَيَقُولُونَ اللَّهُ، فَقُلْ أَفَلَا تَتَّقُونَ}Say: Who provides for you from the heaven and the earth... and who controls the affair? They will say: Allah. So say: Will you not fear Him? [Yunus 10:31]
This verse shows that provision, ownership, giving life, causing death, and control of all affairs are in Allah’s hand alone.
{قُلْ مَنْ بِيَدِهِ مَلَكُوتُ كُلِّ شَيْءٍ وَهُوَ يُجِيرُ وَلَا يُجَارُ عَلَيْهِ إِنْ كُنْتُمْ تَعْلَمُونَ . سَيَقُولُونَ لِلَّهِ، قُلْ فَأَنَّى تُسْحَرُونَ}Say: In whose hand is the dominion of all things, and He protects while none can protect against Him, if you know? They will say: Allah. Say: Then how are you deluded? [Al-Mu'minun 23:88-89]
All dominion belongs to Allah. Protection, victory, and refuge are in His hand, and no one can prevent what Allah wills or repel His judgment.
{مَا يَفْتَحِ اللَّهُ لِلنَّاسِ مِنْ رَحْمَةٍ فَلَا مُمْسِكَ لَهَا، وَمَا يُمْسِكْ فَلَا مُرْسِلَ لَهُ مِنْ بَعْدِهِ، وَهُوَ العَزِيزُ الحَكِيمُ}Whatever mercy Allah opens for people, none can withhold it; and whatever He withholds, none can release it after Him. He is the Mighty, the Wise. [Fatir 35:2]
This verse plants in the heart that giving and withholding are in Allah’s hand, and that no created being owns benefit or harm for itself or anyone else except by Allah’s permission.
From the SunnahEvidence from the Sunnah
The Prophet ﷺ nurtured his Companions upon attaching the heart to Allah alone and knowing that benefit and harm are in His hand.
O young boy, I will teach you some words: Guard Allah, He will guard you... If you ask, ask Allah; and if you seek help, seek help from Allah. Know that if the whole nation gathered to benefit you with something, they would not benefit you except with what Allah had already written for you...
Narrated by At-Tirmidhi, who said: hasan sahih.
This hadith contains a great explanation of the meanings of Lordship: benefit and harm, protection, success, and decrees are all in Allah’s hand. The intended meaning is that the heart attaches to Allah, asks Him, and seeks His help in what only He can do. As for seeking help from a living, present person in what he is able to do, while believing he is only a means and that success is from Allah, this does not oppose tawhid.
