allah is sufficient

Whoever puts his trust in Allah, He is sufficient for him (for all his needs). Allah surely executes what He decrees; assuredly Allah has appointed a measure for everything.
—  Holy Qur'an, at-Talaaq 3
I attempted to thank my Creator, who has blessed me with far more than I can count, but found myself unable to do justice with my words. I attempted to express my gratitude, but became conscious that He will always give me more than I can be thankful for. To thank does not suffice, for words are but limited. All which He bestows upon me will always outnumber the capacity I hold to be grateful. In my attempt to thank Allah, I came to realize the immensity of his Mercy. I give Him less than I receive, yet He is more appreciative that I. Allahu Akbar. To thank him; my actions can only show it, my tongue can only utter it, my heart – only he can understand it. Never have I been so honoured to be a slave of Ar-Rahman.

عن أبي سعيد الخدري رضي الله عنه قال: “إن ناسًا من الأنصارِ، سألوا رسول الله صلَّى اللهُ عليه وسلَّم فأعْطَاهم، ثم سألُوهُ فأعْطاهم،حتى نَفِدَ ما عندهُ، فقال : ما يكون عِندَي من خيرٍ فلن أدَّخِرَهُ عنكم، ومن يستعْفِفْ يُعِفَّهُ اللَّهُ، ومَن يَستَغنِ يُغنِهِ اللَّهُ،ومَن يتَصَبَّرْ يُصَبِّرْهُ اللهُ، وما أُعطيَ أحدٌ عطاءً خيرًا وأوسعَ مِنَ الصَّبرِ.” صحيح البخاري

Narrated Abu Sa`id Al-Khudri: Some Ansari persons asked for (something) from Allah’s Messenger (ﷺ) (p.b.u.h) and he gave them. They again asked him for (something) and he again gave them. And then they asked him and he gave them again till all that was with him finished. And then he said “If I had anything. I would not keep it away from you. (Remember) Whoever abstains from asking others, Allah will make him contented, and whoever tries to make himself self-sufficient, Allah will make him self-sufficient. And whoever remains patient, Allah will make him patient. Nobody can be given a blessing better and greater than patience.” Sahih al-Bukhari 1469  In-book reference : Book 24, Hadith 72

Allah is sufficient for me; there is no deity but He. In Him have I put my trust, and He is the Lord of the Supreme Throne (as the absolute Ruler and Sustainer of the universe and all creation, Who maintains and protects it).
—  Holy Qur'an, at-Tawbah 129

ٱلَّذِينَ قَالَ لَهُمُ ٱلنَّاسُ إِنَّ ٱلنَّاسَ قَدۡ جَمَعُواْ لَكُمۡ فَٱخۡشَوۡهُمۡ فَزَادَهُمۡ إِيمَـٰنً۬ا وَقَالُواْ حَسۡبُنَا ٱللَّهُ وَنِعۡمَ ٱلۡوَڪِيلُ

Those to whom the people said, “Verily, the people have gathered against you, therefore, fear them.” But it (only) increased them in faith, and they said: “Allah is Sufficient for us, and He is the Best Disposer of affairs.”
