Berusaha Bersama-sama dan Melakukan Perbuatan Baik Terus-menerus

Berusaha Bersama-sama dan Melakukan  Perbuatan Baik Terus-menerus

Di dalam ayat berikut, Allah menyatakan bahwa perbuatan baik yang dilakukan terus-menerus adalah lebih baik ganjarannya di sisi Allah.

“Harta dan anak-anak adalah perhiasan kehidupan dunia, tetapi amalan-amalan yang kekal lagi saleh adalah lebih baik pahalanya di sisi Tuhanmu serta lebih baik untuk menjadi harapan.” (al-Kahfi [18]: 46)

Perbuatan tersebut juga merupakan tanda keikhlasan dan kesucian seseorang. Sebagian orang dapat melakukan perbuatan baik, tetapi bukan karena mereka takut kepada Allah, melainkan ingin mendapatkan kehormatan dan pujian di mata manusia. Sebagai contoh, seseorang yang mengirimkan barang-barang dan pakaiannya untuk orang-orang yang kehilangan tempat tinggal karena gempa bumi. Ia mungkin saja membantu tetangganya, atau bersikap baik, sayang, dan baik budi. Ia mungkin juga ramah, lembut, dan memahami karyawannya. Ia mungkin hormat dan penuh toleransi kepada orang yang lebih tua. Jika perlu, ia bisa saja mengorbankan dirinya, ikut serta dalam kegiatan kemanusiaan. Semua itu adalah perbuatan yang baik. Bagaimanapun juga, apa yang benar-benar penting adalah keteguhan dan kesabaran yang ditunjukkan saat melakukan perbuatan tersebut. Sepanjang hidupnya, setiap muslim yang telah menyucikan dirinya harus membantu siapa pun yang membutuhkan, tanpa memperhatikan pendapat orang lain tentang dirinya. Usaha-usaha yang dilakukan hanya untuk mendapatkan keridhaan Allah ini juga dilaksanakan untuk membuktikan tingkat keikhlasan mereka. Bagaimanapun juga, jika orang tersebut gagal membawa dirinya kepada ajaran moral yang disebutkan di atas dan untuk bersikap dalam sikap pengabdian dan pengorbanan diri yang sama, kesucian yang akan didapatnya saat melakukan perbuatan lain akan mudah hilang.

Demikian pula, ada sebagian orang dalam masyarakat jahil yang mampu melakukan perbuatan baik, bahkan meski mereka tidak percaya kepada Allah. Akan tetapi, mereka melakukan perbuatan tersebut bukan karena rasa takut mereka kepada Allah atau dalam harapan mereka akan hari akhirat. Mereka bertujuan untuk mendapatkan balasan dan keuntungan dunia, besar maupun kecil. Sebagai contoh, mereka mungkin membantu korban gempa bumi hanya untuk membuang barang-barang mereka yang sudah tak terpakai. Begitu pula, rasa hormat yang ditunjukkan terhadap orang yang lebih tua mungkin hanya semata-mata karena pengaruh tradisi budaya. Demikian pula, ia mungkin saja memperlakukan karyawannya begitu ramah hanya untuk membuat mereka lebih giat bekerja dan menghasilkan pendapatan yang lebih. Ia mungkin memberikan bantuannya untuk menolong organisasi kemanusiaan untuk mendapatkan kehormatan dan harga diri dalam masyarakat. Untuk dapat memastikan bahwa perbuatan-perbuatan tersebut dilakukan karena rasa takutnya kepada Allah dan ajaran akhlaq mulia yang diperintahkan Allah, orang tersebut harus menggunakan upaya yang sama dalam setiap detik kehidupannya dan terus-menerus bersikap sesuai dengan prinsip Al-Qur`an. Pentingnya berpaling kepada Allah setiap pagi dan petang, terus-menerus setiap hari, ditekankan dalam ayat,

“Dan bersabarlah kamu bersama-sama dengan orang-orang yang menyeru Tuhannya di pagi dan senja hari dengan mengharapkan keridhaan-Nya; dan janganlah kedua matamu berpaling dari mereka (karena) mengharapkan perhiasan kehidupan dunia ini; dan janganlah kamu mengikuti orang yang hatinya telah Kami lalaikan dari mengingati Kami, serta menuruti hawa nafsunya dan adalah keadaannya itu melewati batas.” (al-Kahfi [18]: 28)

Jika seseorang dengan tulus meyakini keberadaan Allah dan hari akhir, ia tidak akan berbuat sebaliknya. Karena itu, ia tahu pasti bahwa ia bertanggung jawab akan setiap detik kehidupannya di dunia dan ia layak mendapatkan kehidupan yang abadi di surga-Nya hanya jika ia menjalani kehidupan dengan mengikuti keridhaan Allah. Ia bersegera melakukan perbuatan baik untuk mendapatkan ridha Allah dalam setiap perbuatan, perkataan, dan sikapnya. Dengan bertanya pada diri sendiri, “Apa yang dapat saya lakukan?”, “Bagaimana seharusnya saya bersikap agar Allah ridha dan sayang?’, “Sikap apa yang harus saya perbaiki agar tingkah laku saya lebih baik?”, dan ia berusaha dengan sungguh-sungguh. Demikian pula disebutkan di dalam Al-Qur`an bahwa tingkah laku mereka yang berusaha, sebagaimana mereka seharusnya berusaha, diberi ganjaran yang besar. Dinyatakan dalam ayat,

“Barangsiapa menghendaki kehidupan sekarang (duniawi), maka Kami segerakan baginya di dunia itu apa yang Kami kehendaki bagi orang yang Kami kehendaki dan Kami tentukan baginya neraka Jahannam; ia akan memasukinya dalam keadaan tercela dan terusir. Dan barangsiapa yang menghendaki kehidupan akhirat dan berusaha ke arah itu dengan sungguh-sungguh sedang ia adalah mukmin, maka mereka itu adalah orang-orang yang usahanya dibalasi dengan baik.” (al-Israa` [17]: 18-19)
